I read that both models use the same nozzle,but from videos it seems that the Big Shot has a bit bigger flame. I really hate farting torches where flame intensity isnt stable during operation. I am most bothered by flame outbursts ,actually so much that i decided that i want higher end torch. Does any experience any of these with their Blazers ? Does any have both ? Is it really only the tanks size that differs but not the performance ? Which is supposed to be safer for running over longer periods of time ?
