What I can comment on is the freak tip/step bore thing: My years of field testing with different bore diameters of step bore and 2 piece barrels is such: a tighter step bore of about .005-.010" larger than the control bore is the best all around. FPS/efficiency is highest, shooting through breaks seems best with this configuration, and with good porting pattern the sound is excellent. Going bigger does not offer any advantage and in fact seems to shoot through breaks worse, so most 2 piece barrels and freak tips are really not that ideal at all, considering how much bigger they are than .680 paint.
