I got into GInnie Springs this weekend and had a good bit of success. I penetrated about 1,000 feet on the first dive and 1,100 on the second. My buddy turned it when I was only 100-200 psi away from doing it myself. I did get my camera snagged on a line as I was negotiating the Eye Bypass. That was tight, but FUN. We also did the Lips Bypass, but that was not nearly as tight.
Trim felt great: even my buddies thought so.
I LOVED having D-Rings on my tanks. They sit about 4 inches out from the ones that hold them to my harness. I even clipped my pony off on it! YAY!!! I really, really liked this. I need to get a hose that's just a tad bit longer and a side discharge reg and I will be set. The other D-Rings that I put on my neck strap were useless. Grrr. I need to rethink that with possibly a steel ring around the neck. I also could not find my double reg necklace, so I have to build a couple of them.
FWIW, I would love to find a second stage where the hose can be reversed. I want a long hose on both tanks with the hose going from the left on the left second stage and the right on the right second stage.
