After reading the "new" features, it seems like a cop out just to make a bit extra money, the extra long cuts for detents have been on Kila bolts for a year now, and the fact is, the Cure 1 is good enough, i never chopped with the cure 1 or with a Kila bolt, and with the Kila you get the soft tip in the center. The idea is that they updated there upgrade bolt for those Etek users and those who havent got an upgrade for the 05/06 egos, dont get me wrong, im sure that the new design of the plastic will help out in some way, but not worth selling 1 bolt to buy this new one. But if you have money to blow, go ahead.
