Subject: Trimix question
If one were going to use trimix in the deep rec/lite tec range,  as many
have been advocating here, for moderate exposures, ,  say, 100-160', 20-40
minute bottom, and wanted to have a fairly standard mix to use rather than
doing a different mix for every dive, what would one use?

- 17/17 poor man's trimix aka heliair
- Cobb's 20/20
- a nitrox-style hyperoxic trimix, say, 28/30 or thereabouts
- a real trimix, say 17/30
- other ??

How would one plan the dive:
- available tables (which?)
- Cobb's 20/20 tables (which don't exist yet?)
- custom computer-generated tables for each dive
- air/nitrox tables or computers, and ignore the He.
- other?

I have no opinion or agenda here, just curious about how ready trimix is
for use by the non-hardcore-techie.
