I kind of have the mindset that "if it ain't broke, don't fix it."
I've played a Tama Iron Cobra Rolling Glide for a good long bit now, and for my level of ability, it's more pedal than I'll ever need - it gets the job done exactly as it's supposed to.
Possibly, if I was a session guy or something like that, I'd want something that could really be dialed in and a pedal where I could get absolute control over it - i.e., Axis Long Boards, Pearl Demon Drive direct drive, etc. Otherwise....? Gotta stick with the good old Iron Cobra.
