Call me silly, but I haven't 'bought' into the types of aiders that lots of folks are using now. I don't want something strapped to my knee or foot, I'd much rather just climb my sticks like a ladder. If you are using Stepps or something similar these high-speed aiders may be a better option, but I am still climbing with a set of sticks.
I prefer a single length of 1" tubular nylon that I've tied into a 3 step aider. Easy, safe, cheap, effective.
With my lone wolf sticks, I have an aider on my bottom stick and one on my middle stick (both are 3 step aiders) and I can hunt a little over 20 feet with these. [By hunting I mean my feet are above 20 feet].
There are some really cool and inventive aiders that folks have recently been using, but for me I just want to get up the tree quietly and safely so I use what I mentioned above. I'm all about light weight and carrying less stuff, but I know that when the time comes for me to try and stick something with an arrow, I want something reliable and QUIET - that includes me! I don't need to be grunting and scraping tree bark as I climb a tree.
Welcome aboard by the way. You are in for one he!! of a ride, saddle hunting rocks.
