Re: DW or Iron Cobra?
They feel roughly the same... I have the 9000 2 legger and I love it. 2 things though; the hi-hat clutch gradually loosens so you should remedy that with a gibraltar quick release one... and I think the cam is both a blessing and a curse - it makes sloshy, or open/closed playing a breeze, but I think the foot chick is a bit quieter because it's less direct.
I haven't sat down with the tama but just had a bit of a tap of it instore and it felt pretty much like the dw...
Might come down to how its appearance matches your kit or our bass drum pedal?
I agree with Dre25
