Promark Stephen Perkins or Mike Portnoy sigs depending on if I feel like oak or hickory. I play an ekit so the tips don't matter much to me and they both feel good but are not too big for the little kit. On my practice pad I like the Promard Hickory 2B. That being said I'm all about variety - been married 7 years so I like variety elsewhere in sticks, cars, etc. ; )
Sometimes I use the Promard 727 oak on the ekit or the Promark 747 on the acoustic kit at work (high school band room). When other people play my ekit I make them use the Promark 7A nylon tips.
