I have said these two things from the start...
1. Don't buy a boot because of BOA but also don't NOT buy a boot because ot BOA
B. BOA won't make a boot that doesn't fit, fit.
After spending a good amount of time at BOA in Denver, BOA is very addiment that they will not bring their closure system to a product until they are sure that there is an advantage. BOA chooses who and what products they want to work with, not the other way around.

I think every (major) boot brand will have some BOA boots in ther collections next season. BOA is here to stay. As far as breakage and longevity, I have yet to hear of one breaking and and the skiers here will be on their second or third pair of boots before one would need to be replaced.
