i got the FP8500B (belt drive). one of the best pedals i have owned. came from trying to replace my old 1990 yamaha pedals. loved the FP8500B so much i got the HS1200 hi-hat stand as well, also very very incredible. you cannot go wrong with these pedals.
i bought after trying DW, tama, pearl. all were either too heavy, too expensive (dw 9000) or just an odd feel. the yamaha is smooth, fast & great design.
