Not sure what you guys are doing, but I thought it would be good to discuss it....here is my tentative plan...
Sat. - Dixie Arrow - 90 fsw - I will do the first dive on AL80 doubles with 38% (ppo2 1.4@89fsw) or so and since the Lindsey has a compressor on board I will top the doubles back off to about 30% for the second dive.
I will get my doubles refilled that night and pick up a rental tank both with 30%...(ppo2 1.4@121fsw)
Sun. - Proteus - 120 fsw - I will do the first dive with my doubles at 30% or so and then use a large single tank with 30% (100-120) for the second dive.
