Quck question on Stud software

[Gonso]

I've played a fair amount of Stud, Stud Hi and Razz, but I've never gotten into it online online. I picked up the Stud version of pokertracker and am more of less ready to go.

Could someone tell me what software a typical online stud player is running besides PT? I'm not talking about the programs that memorize hold cards (and I did read the FAQ). Is there a commonly used HUD similar to the ones common in the other games?
