I used to shoot a lot of 35mm color and I always used an SLR on a tripod. When I started shooting more black and white, I bought a Leica and stopped using a tripod. It really wasn't the color vs black and white thing that changed my tripod use, it was due to a change in subjects. I started using 35mm for subjects that were more dynamic in nature--where the print quality was secondary to the subject matter.
