its the second fastest option IMO. I have a macro set to (R2+L2)+O because i'm already switching targets using the trigger buttons... I "feel" it is faster that way... Other than L2+R1 (finding target) then square then up then X. It's more like L2+R1 (finding target) add R2 to the mix then press O. lol. Feels more fluid IMO. but i really would like the option to just press R3 when i have a target selected.
