I've been to Cozumel a few times and clearly there are many types of divers, vacationers, preferences, etc. And like 'Coz Sally" just wrote, please don't be so quick to write off Cozumel. To me Cozumel is like a favorite restaurant. You're always going other places, yet every so often you return to favorite spot because there's just something about it
For me (w/r Cozumel) it's getting there in under 4hrs (non-stop), excellent diving, great food and darn good prices when it comes to a dive trip vacation.
I would also second some of the other members suggestions regarding researching an approrptiate dive operator for your diving preferences. Hopefully you can find an operator who will cater more to your equipment configuration, site preferences, profiles, etc.
Personally, if you can't find an operator who is fully on board for the SCR/CCR rigs and profile potentials, I would recommend leaving your rig at home for a place like Cozumel. Because, as soon as you get on a boat with the normal mix of experience levels, you'll be looking at a dive profile that may greatly undersell the capabilities of your system. And to compound things, the stealth of the SCR/CCR probably won't pay off (ie critter spotting) down there because you'll either be so far ahead of the group in those currents that you'll be at a greater risk of being lost. And if you're hanging back, the other divers will spook the occassional Nurse Shark or Eagle Ray before you get there anyway.
So I'd recommend at least one more trip there taking a different approach. Dig out your OC rig and pack it up. Fly directly into the island (as you did). Stay someplace a bit cheaper and closer to town (Casa Mexican is nice, still a bit spendy though). If you want breakfasts, try places in town (ie Jeanies, Palmera's, Rock'n'Java, a bakery, fruit from the Grocery store). Sign up for morning two tank dives with some of the excellent operators listed here repeatedly. Heck, I actually like Dive Paradise because I enjoy the time visiting with people, a covered boat and a head. And book a few afternoon dives too. If part of your SCR/CCR choice is managing PP02, avoiding deco, longer dives, etc then find a place with 100's or 120's and order up EAN36 for your second shallower dives. And when you're ready to go out and eat, get out of the Hotel every night. I always return to Guido's, Casa La Mission, French Quarter, Casa Dennis, Prima's, Poncho's, etc with my favorite being La Veranda.
Bonus! Cozumel can be a cheap low stress diving getaway. And with your setup, you could easily take advantage of those extra bucks putting them towards CCR trip to Cocos, Galapago's, etc.
