ZX and NatGut Hybrid. Which goes in mains vs. cross ?

I'm heading conflicting stuff on this forum.
What is more standard?
Most people who use zx prefer it as a cross with kevlar mains. A few people really like gut mains and zx cross. Fewer still have tried zx main and gut cross, but that doesn’t mean it isn’t potentially very nice.

I thought you said ZX mains break easily on any mishit?

Can say with certainty that ZX crosses are industuctable if not kinked or nicked on install.

(Never used ZX as a main)

Yes. I have never broken a zx cross on a mishit. For more than 5 years, I used it as cross with kevlar, then re-used the same piece of zx string as a cross several times every time the 16g kevlar broke, which usually took more than 50h. Some of my zx crosses probably have more than 200 total hours on them.

Wow, that is awesome. I’m about to pull the trigger on some Zx pro to use in the crosses with Legend 1.30 mains. Thinking 58/55 in a RF97.

Should I use Zx pro 17 or Zx 16 with the 1.30 Legend mains? I’m a total novice with Zx.

Right on, thanks. That is the only one have used so didn’t know there was a difference. What is the best way to pre stretch Zx?
TypeRx has published a useful tutorial. Any way that you anchor one end and pull with at least 80 lbs in the other end will do. The key is that you want to stretch out all the plasticity until it becomes completely elastic. For an 18-ft piece, stretch it until you get an extra 20” out of (measuring the relaxed length), which takes a few minutes.
Once prestretched fully, it will hold tension better than any other type of string.

Ok thanks, this should be good. Using Gut/poly and the Gut is lasting a lot longer than the poly. Strings are staying in my frames for a long time until the poly bags out and I end up cutting the strings out. Thanks

How does it do pre-stretch on the machine or double pull on a lock out stringer?
@USPTARF97 - I know I should know better as a former professional stringer, but I do not prestretch Zyex anymore. Instead, I set my tensioner for 10% over desired tension and double pull, counting to 10 with each pull.

Why? I’ve found that this is the most consistent way to deal with Zyex’s tendency to be inconsistent during the stringing process. When I was stringing for H-bird and several tennis clubs, I found that it was hard to get consistent string jobs done with Zyex, even with racquets done back-to-back. So, I decided to be as consistent as I could during the stringing process, which made me eliminate the pre-stretch routine...I never did develop or use a method for measuring or quantifying just how much I pre-stretched a string. So, I just started using the method outlined above to insure I was at least consistent in the way I was stringing it and it’s worked for me ever since.

Now that I’m only stringing for myself, I’ve even resorted to using my method on natural gut, but only increase the desired tension by 5% in stead of 10.

Just my $0.02 worth...YMMV.

Good luck!

This must be why Ashaway recommends to string the Zx crosses higher than the Kevlar mains when stringing Crossfire. Makes sense.
 
Yes, I find natural gut breaks in about 5-10 hours for me. Starts fraying by the second hour.

ZX breaks in any off center hit. ZX lasts about 5-10 hours for me as well.

Both gut and ZX are very fragile strings that do not last long at all. This is coming from someone who never broke poly, but replaced it after 15 hours.

Unless you hit very flat strokes, Gut/ZX is likely to be an expensive set-up. I hit a lot of spin, and the ZX mains ate through my Babolat Tonic mains very quickly. Way too quick to justify the cost, for me anyway. With Gut/poly, on the other hand, I have experienced 20+ hours of play with the Gut mains still being in very good shape, and that was in a spin-monster 14x18 string pattern. ZX can also be quite rough on crosses if you use the ZX in the mains. I had a 16x19 set-up with ZX Pro mains and Gamma TNT2 crosses and the TNT2 crosses broke in just a little over 3 hours of play time.

I can't see ZX plus any gut, s-gut, typical multi working well for very long.

As ZX elongates, the stringbed will lose tension. ZX elongates a bunch and continues to do so. So eventually you'll have a rocket launcher.

I think ZX could work with poly since poly doesn't care that it's lost a bunch of tension.

Zx holds tension better than any other type of string, provided it’s been prestretched properly.

agree with above, nat gut would be better paired with low powered poly cross...it’s all about finding the setup that has the best balance...nat gut zx seems like itd be too powerful
