depends what you use...
i run:
sp8 with long barrel kit (and almost no stock parts...) - too damn heavy for having a bottle on, so use remote and stock - it looks the mutts nutts for scenario.
ego06 lightweight and perfect for using with the bottle and cover as it allows me to shoot off handed without a damn line in the way.
as for the ion, i'd run it with a bottle and cover, that way the guys and gals will have something for alol occasions.
