Diving Doubles, and how much does size matter?

[josh b.]

Hey guys, I've been out of the scuba pages for a while now, and I have been noticing some tech. stuff on the mnscuba page.  I already have plans for deco. procedures, adv. nitrox, and possibly rec. trimix if I have the time.

The main purpose of this page is the tank size of doubles. I have used them in the past, but have never purchased a set. I do a lot of wreck diving, usually staying between 100'-130', but I plan on going to Isle Royale and doing deco. dives in Wazee and Ore-Bee-Gone in july.  What size tanks should I use that can accomodate 200' trimix deco dives, and yet have them be of an appropriate size to penetrate wrecks?


Thanks for the help everyone.
