I'm surprised this thread is still alive. It looks like it has morphed several times since I started it. I'm a lot further down the the path to the Doria, but I still have a long way to go. I've completed another 70 or so deep (<185) dives since this thread started. Many were decompression dives on wrecks, but most were warm waters. I'm getting ready for trimix in another few weeks. Looks like another couple of summers until I get to see her. I hope she is still worth the effort. I still have to get up and make some more cold water deco dives. Looking forward to the day, but in much of a hurry.
