I have the Tama HP910LW double pedal and love it, but I may need a second pair. I've been thinking about the cheaper version (HP310LW), but I'm not sure if I would save $200 or waste $200 with such a compromise. Is there anyone who had it and tried both? I had a single HP310L for a few days, but it started squeeking.. so I became worried about its build quality, having more plastic parts. Also the deep groove on the heel plate annoys me a little (add glue?). The other difference is the Cobra coil, but that would be easily transportable and can be bought separately. What do you think?
