Replying to Fighting with my shop: need advice

both of my local shops are sayin that they wont tweak the stock brakes on my px12s for my addict's 84 waist because it wont pass the release test and then i wont have the insurance from the shop if anything happens. i know tons of people on fujatives and pe's with regular brakes so i know they can do it. they want me to buy a wide break and i dont wanna pay for it at all, but if my bindings pull out of addicts its not like its just easy to move it back (symmetrical and that id have to pay again cause no insurance). what do you guys think i should do?
