ZX Red 1.27 at 52 lbs CP first impressions
Played almost 2 hours with the Red ZX 1.27 at 52 lbs CP (constant pull). This would translate to about 58-60 lbs on most lockout machines, especially considering how long I waited on my drop weight machine for these strings to fully elongate (at least 15 seconds on the mains and 30 seconds on the crosses). I strung it at the same tension I would string a typical multi in this weather. The elongation of this string could be a problem if your local pro shop stringer doesn't have the patience to wait that long and doesn't have an electronic CP machine (which would be the quickest way to string it right). To minimize tension loss, I did a one piece string job, tying it off at the top and bottom crosses. If you look at Richard Parnell's video in the Stringing Techniques forum, that's a similar pattern except my racquet does not require the around-the-world (mains end up at the top). After 2 days just sitting in the closet, it lost 7.7% tension (not bad). After a 2 hour match, the total tension loss was 10.5% (better than your average multifilament). I'll keep track of it after every match to see how it maintains. So far, it looks very good.
I would compare the way this string plays to a soft, smooth, plasticky poly with more power and less spin (but more spin than synthetic nylons). The string movement was almost nil, so the movement was poly-like for the first 2 hours. It really wasn't a good day for me with hard topspin groundstrokes, but I think that was my fault and not the string's. Still, I split sets with an evenly matched opponent by playing a chipping and charging type game, which goes to show that when I needed directional control from these strings, I got it. Touch was a little bit of problem but could be a matter of making adjustments to this new setup. Compared to my ZX/Multi hybrid at 54 lbs CP this full setup at 52 was more comfortable but noisier and more plasticky feeling. I don't know at this point which one I like better. Since I do have some half sets of multifilaments sitting around, I'll probably try a few more hybrids just to see what happens.
Right now, this is my string of choice, either as a full bed or with a multi cross. I think it's worth trying if you want a poly-like string but don't like the tension loss or the discomfort. I imagine that it may not work as well as poly on high powered racquets like the PD or APD. I don't think it's a coincidence that most (if not all) of the play testers here who like the string have low powered racquets.
