Add me to the list. I got a few in trades and I really like them, but am trying to tune the rackets properly, as they are really sensitive to string. Here's what I found:
X-One works really well strung at around 54 and can really grab the ball. At high 50s the racket starts to feel brittle. But strung low 50s it eventually becomes a rocket launcher, at about the time the strings start to fray.
I strung one as a hybrid with X-1, 54 and 42 (Cyclone), and this for some reason is also a rocket launcher.
52 Gosen (M) and 42 Cyclone is the best combination so far in terms of control and spin, at least for me. It's also cheap, but I think some combination of X-1 with a poly would be the best if I can get the tension right.
I tried a full bed of poly and I don't think it works for this racket at any tension. It feels brittle again, and the string pattern doesn't have enough bite to do a really low poly tension like 20.
Next I'm going to try X-1 crosses, Cyclone mains.
