Funny. I just saw this thread and though BD Patch? I don't remember commenting on this.You know, I just went through this. In the end I was just going to buy the Gibralter kick pad. Sound, price, durability, and stability it was a good all-rounder. The others seemed like a compromise in some fashion or another.
In the end my local drum store (shout out to Bentley's) turned me on to a non-working Alesis electronic bass drum module-pad-thingy. It has been working really well for me so far.
It has two spikes and the DW5000 I have attached to it has two of it's own. It doesn't really move at all.
