It's not using smaller cylinders to penetrate farther. It's using smaller cylinders to decrease your RMV.
Sure but, for me atleast, the increase in RMV from using larger cylinders is more than offset by the extra gas being carried. ie, I get further with larger tanks.
My RMV when using smaller tanks and a stage is also substantially more than using larger tanks alone.
Its a no-brainer for, if I'm looking to dive further in... bring larger tanks.

Velocity in the water column is a function of thrust and drag. If you reduce drag you get more speed through the water. Period. Doesn't matter whether you're going into the current or with the current... Therefore, for any given amount of gas or time, you can get in further and out quicker with smaller (less drag) tanks. Still, the added time gained with bigger tanks usually makes up for the extra time required to cover the distance and then some.

The logic in using smaller tanks to penetrate further escapes me.

They aren't doubled up, but I've been thinking about selling them since I got the rebreather. I think I still have the bands and manifold bar somewhere. They may be holding a door open or something...

Nice thread, all of my doubles experience has been with 104's and being 155 pounds they were a pain on land. Tried out some LP95's this weekend and loved them, considering my size I think I'm going for the 95's now
