5 - (3 or 4 would be perfectly fine so I'm more than happy with that and like to keep a rotation.)
Too many in all honesty, around 20 something

Depends on the atty combination, with around 40 or so the permutations are such that I could go a couple of years without using the 'exact' same set up!!!!!A different mod, everyday for a month, almost. Must be nice
