Damn fragile carts? or maybe not! I had a XX2 mkII 3 years ago, broke it before 100hrs. I then broke 2x XV-1s in a year(both still not run in), 2 other close friends of mine broke theirs last year! i have since moved to Colibris(2x) which look more fragile but no accidents! I think the reason is that they dont have protectors. Nerves of a bombsquad technician are required with protectors in general.
