I have decided to go with the backpack. It's actually going to look really sweet. Anyway, here's where we are currently at.
I've cut the clear PC chamber to fit the length of the C2 body and now I'm working on the 150 pump configuration.
The 150 pump is simply too big to set up within the C2 shell in the traditional manner. The tubing that goes from the pump to the PC will have to be external of the shell. I will play off this and try to make it look like a stylistic as well as functional feature.
I could bring the tubes out to the side.
Or I could have the tubes exiting the bottom of the shell. I'm probably going to bring it out to the side, and if so I'll have to try to decide between the right or left (I'm right handed) for ergonomic purposes. What do you think?
