The PCC guys (I have one as well) get all hyped up when they get the HOA. It is very easy to put "hard leans" requiring them to shoot weak hand in any stage, or do huge transitions which will slow them down, or speedshoots with mandatory reloads. Instead, I prefer not to change the stages and kick their butts on the same stages we normally run.
I routinely beat 99% of the PCC shooters at my club with an Open gun, other than strong hand/weak hand Classifier stages. (I think the HF should probably change dramatically on those stages). To combat that, we don't do a lot of Uprange starts, or SH/WH stages just to save the 1.2 second advantage the PCC have on those stages.
I laugh when we have PCC only matches, and they have to shoot off-hand on a plate rack at 65 yards and start to complain about how tough it is. Yeah, a rifle stage with 8 inch plates at 65 yards is more of a challenge than a stage with a plate rack at 25 yards.
