7 3/4 Hawk Helium super-mini sticks to the tree like it's welded on. Go for it
Why though? Unless it protrudes and catches stuff the way you pack it, I just don't understand. Not calling you out specfically, I never understood the mini stick thing from the get go.
Not sure if you mean me or the OP, but an 8" packaging would be about as small as humanly possible. And in my case, I already have the 30" sticks so I could have both the tiny version and the regular mini version available to me. I've thought about cutting down my 1-stick 30" long helium to a shortie, but didn't like the idea of wasting the top.
First you shorten the stick, then you dream about a system that's just a bolt to hang an aider and a cam cleat on a triangular standoff, then you lost the standoff and dream up a cam cleat and aider attached directly to a tether, and then you dream up how to replace the cam cleat with a hitch or passing the cord through the eye in the end of the tether instead and BAM all of a sudden you're into 2TC.
