are you saying that veracs and proselyte has more strength bonus than bandos? because last time i checked prayer bonus doesn't help you kill monsters faster. bandos + fire cape is the best armor and cape for melee slaying on every task but waterfiends. they use more prayer potions (15 doses of prayer potion, worth 24k gp, per hour vs. proselyte, verac's skirt, and SW cape), but they actually help you kill monsters faster. technically overloads are always the best to use. however if you do any amount of boss hunting, even if you used the overload method to 99 herb, your overload stock will inevitably be depleted. my personal choice is to use overloads whenever i am cannoning and meleeing, like black dragon tasks, bloodvelds, etc. and to use extremes on uncannonbale tasks.
