Question about MadCatz R.A.T. DWS

Just an FYI - I had a rat 7, and was pleasantly surprised to see that the parts from the old model are compatible with this one - in particular the raised palm support. Unfortunately no adjustment for the shoot angle - but I guess a 3d printed addition should do the trick (It wasn't the part I adjusted most often). (For the sticky rubber - scrubbing sponge + washing up liquid works fine).
