Yamaha DTXpress/DTXplorer/DTXtreme

I've been having problems with the response of my PCY60's, which I've
never really been happy with. At first I was having a tremendous problem
with missed hits, and spent a lot of time jiggering the mounts and fiddling
with the rejection settings, to no avail. Finally, I looked at the circuit 
boards and discovered cracks in the solder on all four solder points for 
the input jacks on both cymbals. Resoldering those points seems to have
cured the missed hits problem.

However, it has done nothing to solve my other problem, which is erratic
volume response. If I take a TP80 and play a steady beat, I can keep the 
trigger levels fairly consistent, e.g.: 61%, 65%, 63%, etc. If I try to do 
the same thing with the PCY60, the results can vary anywhere from 99% to
20%, with no apparent rhyme or reason. Even a really good thwack can
sometimes register only at about 20%. This happens whether I'm playing
8th notes at 180 or quarter notes at 60. Let me note that I already try to
play solely on top of the Yamaha logo since anywhere else seems even more
unreliable. 

Any thoughts on the cause of this? Bad soldering job, bad mounting job, 
bad technique, dead PCYs?
