Here we go:
Ambush EVERYTHING
District everything but bars
100mm wheels in general
Non-freestyler TSI decks
Flex fenders
Lucky decks (Varying angle, odd attachment idea, and you need a new brake bolt)
Twan bars (sorry twan)
Proride decks (not because of proride.. the price is too much!)
plastic pegs (any)
only companies that don't make something that annoys me is phoenix, proto, and madd gear
heh
