@Jody , call TW and order one or two half sets of 16g Ashaway Kevlar for 4.95 and then order a full set of Ashaway Zyex 17g. That will give you a pair of stringbeds for about $12/bed. Then string them about 65lbs for the Ash Kev and 58lbs for the Zyex.
This is an interesting thread. As a long time Forten Thin Blend user, I wanted to see what this Zyex string was all about. I just received a set of Ashaway Crossfire ZX and a full set of Monogut ZX Pro, along with a few sets of 17 gauge Head Velocity. BTW, I discovered the Velocity by accident as it was in some demo rackets I tried (in 16 gauge). It is a very good multifilament ...soft and comfortable feel, good spin, decent power, and holds tension very well (which is second only to comfort as my top priorities in a string).
For what it's worth, in a touch/feel test of all these strings right from the packages, the 17 ga Zyex feels as stiff as a poly or co-poly. The 18 ga Forten Kevlar feels the next stiffest, followed by a tie for the Velocity and the Forten synthetic gut (used for crosses in the Thin Blend). The Ashaway 17 ga Kevlar feels the softest of them all and bends easily. The touch testing I guess means not much as the Zyex when strung in the racket is said to be very flexible and elastic.
In a 100 square inch racket I'd been stringing the Thin Blend at 52 mains (Kevlar) and 57 crosses (syn gut) per manufacturer suggestion for 10% less for the Kevlar, but I may rethink this with the Crossfire set due to the different characteristics of the Zyex. Since its a livelier string my instinct tells me to string it even higher for control, but I don't want to inhibit the properties of the string. My instinct also tells me stringing Kevlar (as well as any poly) at high tensions is a no-no, and an arm killer. I may go with my regular tension setup first with the Crossfire and see how it plays. BTW Ashaway recommends stringing the Crossfire at 10-15% lower tension than nylon strings.
I'm also going to try a hybrid with 17 ga Zyex mains and 17 ga Velocity crosses strung at equal tensions and see how that plays. I'm thinking it would play quite well. Will post results from both setups. If I'm not happy with those I may experiment with the higher tension on the mains.
