Anyone else have bad luck with the stick-on vs the crimp on weights? I had one come off my front wheel, took it back to the shop, they rebalanced and said it was a rarity. Well, same shop mounted/balanced a tire for me last week, and now after one spirited ride, the lead was separating from the adhesive. I have it taped down now. I'm just unsure if I should take it back and bitch again, or take it elsewhere that won't use those crappy weights.
