My 3mm Dunlop Stubby Triangles (NOT "big stubby", which are in fact small!!) do just fine! I do have to get them by the job lot from Thomann now, because it seems impossible to find them in shops these days, which is a shame. Still, at least I have enough of them now :) I usually get through one in a gig, or every 4-6 hours of studio practice.
