Best wishes! The special semihollow or the studio would be a nice fit in your PRS stable, especially for versatility. A fiore might be another option to consider. You mentioned you might want something to get on the heavier side of things. A custom 24 Floyd could do that but the bridge is divisive. The Tremonti up route tremolo singlecut could also bring the heavy without the hassle of the Floyd and the up route is unique to that model in the PRS lineup.
