The Iron Cobra range is legendary. Various incarnations are available - chain or strap, true or off set cam etc. My personal preference is a chain driven 'Rolling Glide' - this being a true round cam as opposed to an off set - 'Power Glide'. Tama being Tama, if you for the strap drive option - it's not nylon, it's Kevlar (the stuff in bullet proof vests!), and if you go for chain drive, there are two chains - not one! Good points: a. Beater angle and foot board angle are fully adjustable independently of each other. b. Spring tension adjustment is easy, and because of being 'Tamarised' the spring can't twist meaning you get maximum tension all the time. c. The top of the spring assembly is attached by what Tama calls a 'Speedo Ring' (very secure, but easy to pull off when you want to) which allows for super fast set up and break down, protects the spring in transit, and allows the pedal to be collapsed to fit in the case it come with or elsewhere. d. The hoop clamp is accessible from the right hand side and is not under the foot board. It's also fully adjustable ensuring the foot board is always flat on the floor. Adjustment allows for even the thickest of hoops (up to 14mm). The bad: The hoop clamp has a loosely fitting (allowing the adjustments outlined above) spiky surfaced aluminium foot which is the part that clamps to the inner hoop (Tama call this 'Para Clamp'). WARNING You need some good protection - multi layers of gaffe as a minimum - if you don't want you hoop chewed to bits!! The plain mad (?): There is a spring under the foot board ('Cobra Coil') that is supposed the make the foot board return quicker on the up stroke. Personally, I don't get it and think is just a load of over-design bulls**t. I certainly can't play any faster than on my plain old Yamaha pedal. The nice touch: There is a dual tool - hex key / drum key - supplied to cover all necessary adjustments of the pedal, and it's housed in it's own insert on the left of the pedal. This also means you've always got a drum key to hand because it fits all square tension bolts.
