Get the flat shoe, the little kick out makes a perfect reference point to place your finger every time. I have 4.5s in my pistols and 3.5s in the rifles. They were on sale at Primary Arms during Black Friday for $89.
The PSA EPT was included with my Creedmoor lower, it was better than milspec but nothing like a CMC.
CMC is making a 2.5lb 3gun trigger now but honestly at some point triggers in a semi-auto you may use for realz can get too light.
