Kirschbaum Pro Line Evolution

My test of Dunlop Explosive Red finished with the string breaking, and I was thinking of trying another round string. I dug around in my stash and found this:


This is not the current packaging, and I'm pretty sure I've had this string set for **several** years. So, a couple of questions.

1) Does anyone know if the string formulation has changed over time?

2) Does anyone have experience with poly strings degrading from just sitting around over a long period of time?

I'm interested in this string because it got such a high spin rating from the TW test. Any user testimonials?

Having only used it for 4 stringjobs, as a cross with multi mains, i will say it’s very comfortable, loses tension slower/less than yonex poly tour pro, my previous favorite poly cross. I’ve tried it at 50lbs and 48lbs. Impressive, in a sustainable, consistent way, not the Tree For Two Hours Then Drop Off A Cliff poly way.

The string should be fine as its still in packaging and made out of plastic. Won't have the same issues as old gut which can still last for years if its .

Yes, it maintains tension relatively well and is prestretched at the factory. Due to prestretch it does lose elasticity a fair bit though and I had to cut mine out around the same time as other polys or just slightly longer. It has a really solid feel and nice spin. It is quite comfortable and it takes low tension really well. It isn't the softest string however, it has a different comfort to PTP or RPM Blast Rough which are quite soft feeling.

Overall its a very nice string, does everything well but no huge bonuses over other strings. I prefer RPM Blast Rough for spin and feel over it still and if you want a string that you dont mind replacing every week - solstice power is exceptional.

I bought a reel of it a year ago. Strung one racket and thought I’d made a huge mistake.

Tried it recently in one of my Prince TT310 rackets and absolutely love it.

You have to get the tension right with this string. Initially strung too tight...it felt harsh and I didn’t notice much in the way of spin or power.

Dropped the tension and it’s an altogether different string. Power, comfort and spin are there in spades. It’s now my favourite string.
I have different strings in both of my Prince TT 310 rackets to compare. I keep the best string, cut the other out and try a new string to experiment.

Evolution remains undefeated so far, having beaten AluPower soft, AluSpin main/AluSoft cross and RPM Rough.

I have just replaced RPM Rough with HyperG so I will see if how it compares this weekend. Both rackets are freshly strung.

gave it a try recently, to my surprise, a very comfortable string, strung it at 47 lbs, it does almost everything well, biggest attributes are ball pocketing, comfort and the spin potential. I found it powerful enough and absorbs shocks well playing defensive shots, on offensive shots, it also feels quite controllable for fast swings. I'm surprised this one didn't get much credit compared to similar less-stiff poly strings like Element/Hyper-G/PTP.
Compare to Hyper-G, PL Evolution is about 10% less spin, 10% less power, but 10% more ball pocketing, 20% more comfort, 10% more predictable. PLE feels like PL2 on steroids... would be great if they have 1.20mm gauge.
 
I like this string!

I had a 90 minute hitting session with my son, and like @bxr, found this to be a relatively comfortable but crisp string. I strung it at 50 pounds in the center mains and 46 pounds in the center crosses, and agree on a very satisfying feeling of pocketing the ball. Directional accuracy was good, and it was a bit above average in power. I was recently involved in testing the Dunlop Explosive Red and Diadem Flash, and found that spin with Proline Evolution was good, just a tiny bit below Explosive Red when it was new, and clearly better than Flash - however it's not really comparable to a shaped poly. Power was much higher than Explosive Red and a bit higher than Flash. Volleys were solid and the feedback gave me really good confidence the ball was going where I was aiming it. Sensitivity to incoming spin was fairly low. The only area where I had difficulties was in my backhand slice. I just couldn't seem to find the range. I'd either high a high, floaty shot that would often drift long, or I'd pull it down into the net trying to get a lower trajectory. Launch angle was average, but seemed to be higher the more I hit firmly through the ball. The strings return to their start positions very easily, and the stiffness of the string seems to limit their movement. There seems to have been minimal tension loss despite a lot of very hard hitting. We fully wore out six balls. I didn't hit any serves today but overheads were solid and powerful.

It's been a while since I had Hyper-G in this racquet, and then I used the 1.30 gauge. If I had to give my impressions, I'd say it's a bit more powerful than Hyper-G, more like Tour Bite 1.30 in that respect. For my strokes, I think I probably get significantly more spin with any of Hyper-G/Tour Bite/Revolution, especially like when I'm trying to loop back a high shot with a lot of top. I could hit really piercing slice shots with those shaped strings and I never was able to get close to that today. There's a bit of string denting but nothing that I would call notching.

I still miss the extra spin that a shaped poly gives me, and I'll probably continue to use them over a round string despite the issues they cause for my game. But this Proline Evolution is the best all-around round poly I've recently used. I've got 18 gauge sets of V-Square and V-Torque Tour coming on Tuesday, along with 1.20 gauge versions of Hyper-G, Tour Bite, and Revolution. I have one racquet that needs string so I'm likely to try V-Square since it's the new hot thing.

Quick update - I've been testing Tour Bite 1.20 after using V-Square 1.20 and have found the expected lower launch angle, power level, and spin capability, along with higher impact harshness and better control. For the first time in a while, I pulled out my racquet strung with the Evolution 1.25 and it plays **very** similarly to Tour Bite. Evolution has just a tiny bit less ball grip and spin capability but everything else from power levels to launch angle to pocketing feel seem as though they could be the same string.

Ok, Hyper G is gone and Black Shark is in.
Evolution is still undefeated in all round playability, comfort and tension maintenance (at least for my game).
It didn’t have as much spin as Hyper G but it wasn’t that far behind. I preferred it in pretty much every other area.
Not sure how I’ll go with Black Shark...I meant to string up Black Code 4S and picked up the wrong string :)
I will also try VTorque Tour in this racket (great spin for sure). But I’ve got a feeling that Diadem Solstice Power might be the best chance of knocking Evolution off it’s perch.

Played with Black Shark yesterday and I really liked it. Possibly the best so far in my Prince TT 310, but I just want to try it side-by-side with Evolution. I could really hit out without fear of the ball going long...much more comfortable than I imagined and good spin. And to think that I strung them up by mistake :)

These Kirschbaum strings seem to be terribly underrated.

Solstice Power was my go-to string for a couple of years in a Babolat, and it's quite a different feel than Evolution. Solstice Power will give you a lot more bite when you're trying to put a lot of spin on the ball so the angle it comes off the stringbed will be different. And I found that Solstice Power loses a good amount of tension as it ages, though it also seems to be less sensitive to tension loss than other poly strings I've used. It never seemed to get to so erratic that I couldn't play with it, but it definitely changes over the course of about 10 hours. These changes happen gradually rather than suddenly as in some other strings, so you might just instinctively adjust over time but you'll notice it when you freshly string it up again.

Solstice Power worked well in the Babolat but hasn't seemed to work as well in my SW104. For whatever reason, it just seems harsher even though I'm using a thinner gauge and lower tensions. It was a more plush string than average though it also had a crisp sweetspot response.

Have you tried signum pro Xperience? hexa shaped poly that has similar power level of dunlop black widow but tension maintenance/playability duration of hyperG. It won the 2018 award for best string. Curious as to how diadem solstice power compares to that. I used to use solstice long time ago in a different racquet but arm pain made me gravitate away from that racquet and string, not sure which was the cause though...still get residual arm pain from strained bicep after a few hours of blasting balls so my arm is quite sensitive and I steer clear of anything could be harsh. Used volkl cyclone which is similar to rpm blast but with sharp edges and power level similar to yonex poly tour pro but it killed my arm so had to cut it out. MSV focus hex was also okay but Xperience provided more easily accessible power.

I haven’t tried Xperience but I will give it a try.

Signum Pro are another underrated brand.

I haven't tried the X-perience yet. For this first round of string experimentation, I stuck with strings that TW playtesters actually reviewed and the X-perience wasn't one of those. From what you say, it sounds like this is a string I need to get a set to try.

So it sounds like a string with the bite and playability duration of Hyper-G but the power levels a little higher than Cyclone? If I had to say without doing an actual back-to-back, I'd say Cyclone is a bit more powerful than Solstice Power but Solstice Power has better grip on the ball and a better pocketing feel with about equal tension loss.

Im actually going to revisit solstice power and try poly/poly hybrid with solstice mains// SPPP crosses in hopes of becoming an absolute spin monster...the sharp edged strings definitely provide more spin than soft edged RPM blast or similar imo and it’s not even close. I would advise against using full bed sharp shaped polys because the edges would speed up the notching process so only having them in the mains and matching them with cheap soft smooth round poly with good tension maintenance/playability duration is the way to go. Hoping to find my holy grail setup...

In general, I haven't found too much difference in durability between using a full bed of a highly shaped poly versus using that same highly shaped poly main with a round cross. Maybe the round cross will get me an extra hour or two, but that isn't enough to overcome my laziness in having to measure two pieces of string, make two extra knots, pull out the starting clamp, and all those other things that make me feel like I need a nap.

Having said that, I notched through and broke V-Square in four hours and that may be the first string that would have significantly benefited from a round poly. But it was too powerful of a string for me to use at this time so I won't have to make that decision.
