Please drop me a line if you're still looking. We do PR cases every day and I know what brands fit by default and which do not. That's why it's always a good idea to always buy from a drumshop where you can get expert help.
For Saturns, you need to buy one size UP in diameter for BDs and FTs. For example, for a 22x20....buy a 24x20 PR case. For the toms, make sure you buy the RIMS model PR cases. It'll have a "R" in the model number.
