i wouldnt say that i have all the answers, but there are much better gearsets that you can get for cheaper.
wow, just looked up how much they cost: $50+ ,give me a set of shs gears for $30 or less any day of the week. and unlike modify gears they dont tell you that you that you have to use a m100 spring or lower. matter of fact i usualy dont run anything less than a m120-m130 on my high speed gear sets.
