Those settings aren't too far off of mine. In any case, the settings aren't going to affect kick very much. It sounds like you need to rebuild your ram or get a new one, and reduce your lpr pressure. The MQ2 can operate with a much lower lpr pressure than a normal gun could. With your Coff up that high, you should be able to run the cocking pressure pretty low.
It depends on what you want out of your setup; slower speeds (11-13bps) with very little kick, or higher speeds with more kick. You can't have higher speeds without adding more kick - sorry. Personally, I set mine to max out at the highest speed I can shoot on semi, and run my lpr just above the point that I get shootdown. It is extremely smooth that way.
For efficiency, you may want to try a lower Son, and raise your operating pressure a bit.
