MPC60II pad questions

Are the pads on the 60II only active in the center? I can hit the corners and it feels like there is nothing there(really squishy) and no sounds triggers. The only reliable point of triggering is pretty much the center of the pad (which is very solid), which makes 2 finger 16 notes a little more difficult. Is this normal? Will new rubber pads make a difference in feel? Also is there a good way to test out the sensor to see if it is losing sensitivity? I do get velocity on all pads but I thought I'd have a broader range, it seems like a very steep exponential curve, and I have to hit it pretty hard.

On another note is SCSI really worth it at this point for a 60II if it has a new floppy drive?

OK so I was picking up some cables this morning at GC and decided to see what the MPC2500 pads were like. Compared to my 60II they are super sensitive, I can trigger sounds from all areas of the pads, not just the center. The sensitivity is what I thought my 60II would be like, I couldn't believe it after 15 minutes of playing it my fingertips didn't hurt. I actually scrolled through all the different pad sensitivity settings and curves and it was still soooooo much better feeling than my 60II. Getting 16th hi-hat notes with perfect response were easy, not the case on my 60II.

So can anybody tell me if I do replace my sensors should I get the similar sensitivity, or at least close, from my 60II? Maybe somebody has a 60/60II and 2500 or experience with both? Just another thing to replace in my 60II

I'd first try just some new pads.
