Yamaha FP9D Single Foot Pedal

I have two of these (2 bass drums). My experience of pedals is limited to Tama Speedcobras and Ironcobras (power glide). I think these Yamahas are heavyer then Speedcobras. Closer to Ironcobras (i love ironcobras). Getting used to these is still in progress, but i can already play maybe 10-15 ppm faster then Tamas (15 min. continuing double bass) only minus comes from plastic parts what are still intact.
