On the field= a fluffy, because it's quick and easy, unless its a chop, and not a barrel break, because if its a chop, theirs nothing really you can do.
Off the field= One of those orange pull thro's (not a straight shot) with a cloth on the end, then a nice clean fluffy thro it will sort most things out (dont use a fluffy on a carbon fibre barrel tho)
