Im a recent convert to gut/poly, and after only a few times out with this setup, I am sure my wallet is going to be a lot thinner. The arm sure is happy
Ive been using a Blade 98S with Babolat VS 16 mains (natural) at 62 and Signum PPP 16L (light blue) at 54 and I find it fantastic. I chose the Signum as when I used it in a full bed, I found it to be lower powered (compared to Ripspin) and also to hold tension well (so I thought it would make a good cross). Plus, I had a bunch of it on hand as I bought a reel and didn't like it all that much in a full bed

I am finding the easier power of this gut/poly setup very enjoyable, serving is incredible, and volleys are better than they've ever been (by far). After 8 hours use, the VS is in surprisingly good shape with only light fraying and minor notching. (As a reference, the Ripspin I normally used prior would have been notched 1/2 to 2/3 through by this time, and close to either breaking or playing so badly it was time to clip it out.)
I have noticed however that the launch angle is actually lower with the gut/poly than what I am used to (I previously strung the Blades with the mentioned Wilson Ripspin 17 at ~55). Ive been adjusting to this by trying to increase net clearance. However, if I change the tension on the crosses relative to the mains, can I get a higher launch angle? What would you guys suggest?
I do plan to string the VS mains a little tighter on the next stringjob (maybe 64-65).
