Why not the 7000's? I'm deciding between the 7000's and the Sonor Giant Step.
Sorry, let me get this right. You're deciding between a intermediate level pedal (the 7002) and a high end model (giant step). Does not make sense at all.
To TS, I can give you a rough run down on the pedals to give you a better idea.
The 7002s are not worth it at all. If you're getting the 5002s or 9002s, by all means go for it, you can't really got wrong with it, contrary to what the DW hating bandwagon says. The 7002s are single chain, and lack the adjustability that the higher end pedals come with.
The Iron Cobras are built like tanks, and are undoubtedly one of the most, if not the most, reliable and sturdy double pedal out there. However, you sacrifice sensitivity for this, as the IC may seem a little sluggish and heavy at times. If you like to "feel" the pedal under your leg as you play, then the ICs maybe the one for you. If you're a "plug-and-play" fan, you might want to consider the ICs too. You'll understand after reading about the eliminators.
The Eliminators are not as sturdy or "tank-esque" as the ICs, but they do hold their own ground. They're sturdy enough to last you for a while. You don't sacrifice any sensitivity or adjustability for this pedal. In fact, one of the reason why I sold off my elims a while ago was because I was too irritated with the amount of stuff I could adjust. You have a choice of adjusting:
1. Beater angle
2. Footboard angle
3. Spring tension
4. Cam on pedal
5. Position of footboard
You can achieve pretty sweet "feels" on this pedal if you spend enough time tweaking and playing around with all the various combinations of cams and settings. However, if you're the kind that lacks patience and wants to play on something right out of the box, the elims might not be the one for you.
p/s: oh yes, if you do get the elims, be sure to get the kevlar bass patch from yamaha... i played on my elims using the red cam (super-offset cam) at highest spring tension, and i punched a hole through my bass skin AND a normal bass patch.
