Despite owning a 30mm “extended cant” Super Precision mount with no built in cant for elevation, I can’t give experienced advice, but consider giving Geissele a call...it’s what I did and they were somewhat helpful. The people you talk to are not the most technical, but if you’re friendly they’ll go to great lengths to correctly answer all of your questions. I also called other manufacturers with similar products and they kind of “filled in the gaps” for me. The most helpful response was an email from Spuhr. Follow the question format listed on their website such as you’re intended use, distance you’ll be shooting etc and they’ll recommend a mount tailored to your preferences. If you’re only choice is Geissele, take the knowledge Spuhr offers, and apply it to the most similar Geissele mount.
