Yamaha DTXpress/DTXplorer/DTXtreme

One more item to the kick tower thread(btw, I have no problem with mine).
After trying to figure out how to add a second kick to my kit
I finally stumbled upon a solution. As the kp80s is really not available
(nor our the dual zone pads for that matter-yamaha has some serious production problems)
I found an old snare practice pad I had(the suction type-plus percussion). I cut the outer area
out and cut a slit in the back to reveal a thin plate which is about 6" in diameter.
I then disassembled the dtxpress kick tower removing the small kick pad and piezo element and 
inserted it into the practice pad, using a small drill and some sheet metal screws
I attached it to the front of the tower and reassembled the rest of the tower
and tested the pad for striking coverage, it worked great, so I was able to buy a
double pedal and play double bass like I originally wanted, without the cost of buying
extra hardware. If any one wants more detail let me know, I'll try and get some pictures.
Back to my earlier thoughts on Yamaha, does anybody know of any
source that has stock on the yamaha pads. Most places I have checked 
with say mid April is the earliest. I got tired of waiting and bought a pintech
concertcast(mesh head) for my snare. The rim trigger will work on 9/10 but not on 1-8 rim
trigger inputs on the dtxpress module. Any body know about the dual zone cymbal pads?
will they work on the stereo inputs of the dtxpress? I'd like to add some more cymbals
to the kit-two is simply not enough!
