BCY has done it again. They have taken the best HMPE (SK90 Dyneema) and blended it with just enough Vectran (17%) to make their best string material even better.
They are calling it "BCY-X". It wasn't going to be unveiled until the 2014 ATA show, but it's just hard to keep something this good under wraps. Two of the top wheel companies have already switched to it--one after only a week of shooting.
I've had a sample for maybe a month. Wasn't talking about it for a couple of reasons: One, it wasn't going to be available until next year; and two, I wanted to get some feedback on it.
The feedback so far has been outstanding--on both sides of the sport. Extremely stable--this stuff has practically no stretch/creep once shot in, even in higher temps. Extremely durable--the highest grade of Dyneema available, with a low percentage of Vectran. Reports so far have said it's also a very quiet material--quieter than 8190.
The test strings I've sent out were NOT ultra-low strand counts with anything extra wound in or done to them. They were 18-20 strands, endless and flemish. The flemish have the loops padded out with B-55, as I do with any HMPE flemish string. That's it. No bells and whistles, no smoke and mirrors.
I think this new material is going to knock some of the older ones off the shelf--just won't be a need for them.
It has a very small diameter--just a hair larger than 8190--so even with 18-20 strands, it's still a small diameter string.
Very versitle--with the smaller strands, the strand count with varying draw weights isn't so critical--18-20 stands should be good for 35-75 pound draw weights.
Color selection is still limited--all I have on hand right now is black, but I'll be stocking up on colors soon.
