We seem to have this kind of coversation quite often. I have accused people of misusing equipment causing it to break i.e spurs, rotostarts. I can assure you i have tried my hardest to baby the pullstarts but they are just annoying me so i am swapping my collari (when they bring a backplate out) and 18ss to roto start but i will leave my T 15 as pullstart as i have never had a problem with it
