I agree with Stringreen. Set VTF first and do that with the arm as close to level as possible. The index card trick makes it easier to judge this with the taperred arm. Depending on what scale you use, you'll likely have to raise the arm for this measurement to have the arm level. I f you don't have the arm level, your VTF reading could be off by as much as .3 grams or more. This is the equivalent of measuring VTF at the level of the record(as the expensive Wally scale does)provided you then set the arm level with the record again when you're done. Once the arm is level with the record, lower VTA by 5 at a time until you find the spot you like.
Stringreen is probably right about the soft feet and anti scate as well but I'm still messing around with those on my SSM ref. The rim drive seems to work best with very light conact with the super platter. Not much pressure is needed. Mike at VPI told me if the platter spins a little longer than the flywheel on shut off that's about the right amount of contact. Also, where the platter runs the fastest is another indication that contact pressure is good. The drive belt does need to be in the "land" between the grooves in the metal area and probably best as close to the middle of this metal area as possible. Luckily, raising and leveling is easier with the mini feet than the older cone feet. Probably the mini foot's best selling point in my opinion.
