I don't shoot from a tripod because my sessons are very active. Cats move. A lot. So I have to move. A lot. However, keep in mind that my stobes effectively freeze the action, not my shutter speed. That said I'm often shooting at 1/250 with strobes and with an IS lens (stabilized) all of this minimizes camera shake. The more likely problem is subject motion, but again between the strobes and the shutter speed I don't see that much of a problem.
