Update. Went with Costa Rica Dive and Surf in Uvita. Seemed like a really great run operation. Nice DM's, staff, location, etc. Good comprehensive briefings from top to bottom. Snacks, waters, lunch after tank 2.
First dive cano island, front right side. Lots of morays, large stingrays (southern?), white tip sharks, turtles, fish. At one point I could of put a turtle, white tip, and stingray in the same frame had I had a camera.
Second dive was offshore a bit at a location that sticks up almost to the top of the water. Something 'diablo' I think. Saw a huge school of Barracuda and alot of large snappers. Was there waiting for whales or manta's but nothing came through. Some current to swim against, burned through gas a tad fast, but it was fun. Rental gear was very solid although my reg did seem to breath a tad tough, but I dealt with it.
