Mag bag stiff to operate. Thinking of trying it with 11 septum’s. Any comments?

Do you mean Bag Magazine, aka Bag Mag?

What's stiff, changing septums after an exposure?
Try cleaning the septums then polish them with car polish or wax, just the edges and backs, not where film goes.

Rubbing the slots where the septums slide with paraffin also helps.
Dry film Teflon lubricant may be another choice for the slots and septums edges.

I have tried most of what you have mentioned not much luck.
