Depends on the situation. For street-type stuff the tripod can sometimes be a liability, so faster films and the same holding/breathing/triggering techniques I use for high power rifle competitions are the orders of the day. For landscape shots (yes, those CAN be done with a 35mm) I use a tripod and MLU. In those situations I've often joked that, if I could afford a forklift, I'd use a 2-ton block of concrete for a tripod. In short, I try to use the tripod with all formats whenever possible. When I shoot without one I'm prepared to accept the lower percentage of "keepers."
