You gotta do what you are comfortable and enjoy doing. In the end, your hunting journey is in your hands.
I would like to make a few observations in good spirit.
If you went from climber right to saddle and wild edge Stepps with aiders, you really bypasses some intermediate steps. It may be better to get a 3 pack of sticks and use them without aiders until you are comfortable. Then reevaluate other methods of climbing.
20’ is not some magical number. It co-insides with the number of digits on our hands and feet. Numerous times I have hunted better 6’ to 12’ to my feet. Just high enough to have a good view and have cover.
It seems newer saddle hunters are enamored with carrying the least amount of weight to and from a setup. Not sure if having that as the main goal is beneficial. Maybe think about safe, comfortable, fun (in that order). Then think about fine tuning with weight, if that is what you want.
When in a climber, I believe it would be safer to use a tether and advance it every move you make. I don’t think a lineman’s belt is good application with climber.
Have fun this season and do what makes you happy. And stay safe.
