The "single 12-gram changer" rule is imho obsolete - today most efficient SC markers are able get 40+ full power, fully consistent shoots even with "rapid fire" trough chrono (= commonly even more in game, where has the powerlet time to warm up again, after the chill from CO2 expansion during shot).
40+ are imho for majority of the SC players enought to do not need change powerlets. 6-packs, turret changers and even CA tanks are then no advantage. CA tanks perhaps only saving costs for gas and allowing using wothout disadvantage less efficient, easily accessible markers, but they making the marker bigger and heavier.
You will have surely not advantage with CA Tigershark above stockgun from PPS or Carter.
