I am a Tec Deep and Tec Sidemount Instructor, you dont have to be a cave diver to dive sidemount. I dive sidemount, unless teaching an open water class. If you are interested, you can take Tec training in sidemount configuration, which has lots of benefits and uses for deeper, ocean and wreck dives as well as when traveling. can be hard to rent backmount, easier on and off the boats and shore entry/exit.
I dive with Scubadelphia 267-343-5590. Often at Dutch Springs, but then usually with a class so not much time for fun dives. check it out, may be what you are looking for. Pura Vida joseph
