New topic: DIR vs. DIW

[Vtach]

I believe that most of the manifolds selling right now will adjust for either 7.25" (steel/alum 80) or 8.00" (steel 95 or 104). Bands on the other hand should be tank specific. If you have the wrong size bands it may significantly stress the manifold and cause a catastrophic failure (worst case scenario). Highland millwork has some good information about bands, manifolds and doubles setups.



The only real cost difference between a double set of 80's or 130's is probably the price difference of the tanks. You can find PST 80's around brand new for around $150 each. PST 130's on the other hand, are running around $250-$300 each new. I have gotten pretty comfortable with diving double tanks and I have been diving my double 119's on all my dives since I went to a DIR setup. But they are HEAVY!! I plan on getting the 80's for most dives and using the 119's for Trimix. The double 80's will be more than enough for most dives and I hear that they are VERY comfortable both in and out of the water. If you do plan on larger size tanks, I would lean toward the PST E8 130 (old LP 104). The do not weigh significantly more than the E8 119's but are a bit longer and more balanced than the 119's, not to mention a bit more gas volume.
