Deer Man, you make a solid point that has bothered me since I stumbled on this great site. I use climbing beaners in the configuration of A and B since I see no practical way for me to use C (even though as you point out, C is the correct loading format.)
And just as valid as your point, so are the points of others who state that the loads from A and B are slight when using the suspension system this way. I recently switched from gated beaners to 23 Nano's because they fit in my carry bag easier. But, honestly, I do feel safer with the gated Attache ones using the A and B systems.
