No different with the SDS, different pulley positions are different diameters and will yield different speeds. You can verify it with the friekert app and test disc. The different pulley positions are for those that don't have the SDS to get as close as they can to 33 or 45 since without the SDS you have no control over AC frequency. With the SDS you don't need all the different pulley diameters since you can control AC frequency and optimize any of then for perfect speed. Adding another belt at different pulley diameter just upsets that balance.
VPI Classic tweak
So I ordered a spare belt for my Classic One to have as a spare and when I got it I looked at the table and thought...Hmm why not try 2 belts? After a little research I did find a post on another forum from Mike at VPI who stated that a second belt should open things up a little bit and it did. A little bit more focus and imaging is what I observed. I found no discernible difference in platter speed. At 26 bucks it's a relatively cheap tweak plus the platter looks pretty cool with 2 belts.
