TSI: Good: customize the deck plate, pretty fricken strong, steep headtube angle, awesome break
Bad: many have broken (idk about the new reinforced though), HEAVY
Ultra pro: Good: Light
Bad: breaks easily, short deck, crappy brake
Lucky: Good: Choose from 3 different decks (light, 4.5pro, 4.0pro), the light deck is lighter than a regular pro, the pro is only 6 oz heavier than a pro model, good headtube angle, absolutely NO welds, very strong.
Bad: ..................................idk? you have to bolt on a headtube? thats the only bad thing i can think of although its not really a bad thing..
