How about combining carbon bolts and a climbing stick? Instead of a double step just run CF bolt thru a stick top and bottom.
More weight... might as well go Aluminium... welded aluminium sticks are very light.If you could get a metal end cap and attach the steps to that you could drill a hole in them and run, either a cable with eye bolts on each end on a all thread through it and bolt it down! It might even help with the flexing by compressing the fibers, not sure how that works just brainstorming and not sure how much weight that might add just a thought!

Totally unrelated but I thought you might like to see these given your screen name

All innovative people have to be borderline crazy to try what others have not tried

Good to know the only sticks i have ever used are the old school metal ones! There is a store by me that sells them for $9.95 a piece! Cheap enough to leave on some pre-sets!More weight... might as well go Aluminium... welded aluminium sticks are very light.
Could the step and standoff be welded to a piece of aluminum tubing and epoxied into place on the cf tubing?
Proof that holes in carbon fiber are feasible
Just wanted to add that the way the CF is plyed for prosthetics(and other flat surface applications ie: see aerospace) is a little different than how it is for tubing applications. They orient the ply directions to create the desired support and strength versus less fussing with the ply direction because the tubed structure will have inherent support properties by nature of it's geometry. So not really apples to oranges... BUT... raises an interesting idea: you could probably have incredibly strong and thin CF ply that would withstand shearing forces of steps and bolts if someone were to engineer the plys properly. Caveat to all of this: $$$$$
I worked on a running blade project at my dayjob for a project sponsored through paralympian Blake Leeper. Pretty interesting project. I can tell that the running blades are incredibly strong, but also designed to withstand other dynamic forces such as flexion and torque, not static rigidity.
I apologize as im late to this but have you tried a filler like the balsa wood previously mentioned earlier around step,standoff and versa button areas?
My carbon+welded aluminum stick came in at 15oz. I might go back and try to use real epoxy to hold the ends on.More weight... might as well go Aluminium... welded aluminium sticks are very light.
