As I've said earlier, I'm not a group shooter, only score. I have tuners on everything except my Factory Class 6 BR. I shoot 6PPCs, 6 Beggs and 220 Beggs. I always preload and almost never touch the tuner. Wind reading is nearly everything. From time to time we've had folks shoot PPCs at 100 and switch to a 30 BR at 200. Also, once in a while someone will bring a Dasher. The PPCs still win, once in a while the Beggs. Don't recall a Dasher ever winning one of our matches and the 6 to 30 swaps haven't worked either. I wouldn't argue one strategy over another or even one caliber over another. I just know what I see at matches.As far as the ppc being fussy and load needing to be adjusted thru the day. That's true. But I've found out the more I practice shooting in the wind the less I seem to be fussing with the powder charge
