I finally decided to order my optima. My insructor also informed me that the Optima FX is available. He sent me a press release from Dive-Rite announce the release of the FX. If anyone wants a copy, then just PM me. I dont' know if I am allowed to post it or not.
I'm not sure on all of the changes on the FX versus the original Optima, just what has been posted in earlier threads.
I would like to thank everyone for thier inputs. It helped with my decision of Optima vs. Inspiration.

Biggest advantage is by using 13 cube cylinders (2L) an\ you can shorten the unit by over 2 inches and cut the weight down by 20 pounds the untit with 13's AL weights 48 pounds and in wet suit you most likely will not need a weight
