This is totally my opinion before anyone gets thier bothered hat on, i set my own guns up and these are my findings for the ego...
As a guide start at 85% Band and about 3% tol, keep raising the band until you get to around 90 if its still boucing then your trigger needs adjusting. Back the band back down to around 85 and lengthen the trigger pull, again adjust the band back up again until it stops bouncing, if its still bouncing then back it off again and stiffen up the pull.... repeat the process until the trigger is still comfortable and your not missing shots cos if the filter is too active and you have fast fingers thats what happens, its a pain in the arse really as everyone is different with regards to finger speed, pulling pressure e.t.c
When setting it up make sure you have the gun exactly how you would have it when playing including a hopper full as this definately makes a difference!
Also. get the 'kick' down to as little as you can again i have mine set with around 2 turns in from flush on the lpr with a dwell between 9 and 10...seems to work for me.
This will hopefully get you sorted for now, but if your not very technically minded, give it someone who's **** hot and knows what thier doing like rob ^
good luck!
