@TennisManiac - Understood re- the 100's.
Yes, I think a Radical MP demo is definitely in order. I would expect to add handle weight to bring balance more in-line with the Pro Staff.
As for the 315 ISO, you should demo from an online shop so you can cut out the demo string and put in Alu @ 45 (your regular setup). If your spidey sense says "yes", then beyond that you'll only really ever know the long-term comfort by purchasing, preferably with a matching service. If you have the cash to float, I'd say perhaps just buy right away for the privilege of avoiding an off-spec demo. Worst case, you flip the frames for decent resale value while the ISO series is still mid-lifecycle, and chalk up whatever little is lost as tuition/learning expense.
As for other options, not sure how willing you are to try off-brands, but there's the Fury Arma Pro 98, which is supposed to be a more powerful Pro Staff in both behavior and feel. It can be a bit "hot" in the upper half of the string bed, but perhaps Alu Power would help to tame that well enough. Then again, not much of that matters right now, as it's currently sold out in the US at least.
