I just got a Hoyt Vectrix and I have well over 200 shots through it and I can not see any problems in my strings....yet. I did have a Fuse string leach blow up on me already. I will keep my eye on the strings now. My old hoyt Impulse lasted good it still has the original string on it, I wax it all the time but looks great. Maybe I got lucky with my vextrix and I got the best string in the batch!
