Questions about MadCatz R.A.T. DWS

Question about the wireless connection: When I select Bluetooth, the pointer on the screen is quite "inaccurate" or it stutters, as if you had too few FPS, if I connect it with 2.4G, then the pointer runs smoothly. Can the Bluetooth connection be improved or is it generally worse? I use the mouse on 2 PCs and constantly changing the USB wireless dongle is tedious because it's very fiddly to remove from one device and USB ports are also limited.

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).

I had 3 Mad Catz MMO7, very ingenious mouse! But unfortunately all of them had a loose contact at the cable input, very poor design there. Then I bought the DWS because it's wireless, but unfortunately the design is cheap compared to the MMO7. Does anyone know of a mouse that has as many practical buttons as the MMO7? Preferably wireless. Mad Catz doesn't seem to have anything on sale.
