I have an icebreaker j/b, which i love. been told to switch to the predator bk2. my main question is, whats the main difference in the bk1 and the bk2? I've broke with the bk1 when they first came out, and honestly wasnt extremely crazy about it. it was nice, but just couldnt see it breaking good enough for the price tag. I play with a predator cue and think that predator has all the technology in the world. is the bk2 a lot better than the bk1? should i switch from my icebreaker?
