The only difference there is beast sticks are made from aluminum, which is the material I am staying to stick with.
How are these going to hold up to the repeated pressure of someone sliding them down to cam them into place? What if that standoff catches one good time when sliding it down?
I guess my main point is, why would you risk your life to something that may have been tested in a static position and not in the most likely time of failure. which imo, is the first time you step on the stick and it slides?
I equate this to the Predator failure on the original design. I don't know of any that broke due to stepping on the platform after camming it over. I know all of the failures I saw was on the pressure from the cam action. I am assuming some similar findings will happen in this instance.
I think you are underestimating the strength of carbon fiber. As someone who rode many miles on a carbon fiber framed mountain bike I can assure you that frame took substantially more abuse then my sticks do. Also, the consequences of that frame failing as a I was traveling 30+ MPH down a mountainside would have been as bad or worse then having a stick fail.
Just off the top of my head carbon fiber is used in vehicles, planes, the aerospace industry, windmill structures, climbing spurs, etc. I believe there are some commercial jets that the entire support structure is made from carbon fiber. As long as it is done correctly, I personally wouldn't worry about carbon fiber breaking in a climbing stick. I also probably wouldn't pay the increased costs for the weight savings but, many will.
