i one stick climb with a mini-shikar with the angled scout platform on the bottom with a 3-step aider. It works well, packs easily, and is very light. The question is what is your intended goal? If you don’t mind essentially climbing on the aiders mostly, then go short. That’s what I do, climb the aiders then stand on the platform as I get ready make the next move, or when at hunting height then I’m on the platform anyway.
If you want the extra steps that a stick with two sets of steps provide then I would space it more like 14-15” or so. Anything shorter really is a waste of a stick for that purpose.
This is just my personal opinion.
