trigger is preference. You will want a nice CP trigger when using a microswitch board like the APE board.
The 3shot PSP ramp is a feature of the APE board. I prefer regular ramping to 3shot ramping because sometimes when I let off the trigger, the gun will shoot a 3 shot burst instead of just stopping. Its up to you. If you have fast fingers, you wont need 3shot ramp to be effective in a snap battle.
The APE board has Semi, PSP3, Millennium, NXL, Regular ramp, 3 burst, full auto, etc. You wont have to worry.
The biggest thing to understand about the APE board is that just because it has a TON of settings, you only need to change the following; Dwell, Rate of fire, fire mode. You dont need to change any eye settings or other odd ball settings. Its easy to get confused if you think you must customize everything.
