I bought some Charge Sponge grips as they were nice and cheap, but I've since realised this is probably because the bolts it uses are made of plasticine (yes worse than ODI ones) and I've rounded the heads simply installing them (carefully!)
I've tried emailing Charge twice now as I'm probably going to have to destroy the old bolts to get them out, but have had no reply. Am I likely to get any sympathy from the distributors?
