To each his own.
For trees I find on the fly, I simply put on Sport Climbers (climbing spikes made for trees) and shimmy right up the tree (25-30 ft). I then screw in 3-4 steps for my base (EZ screws), tether to the tree, screw in a hook for my bow and I'm hunting. This normally takes about 5 minutes total, give or take a minute. I keep the screw in steps in a pouch attached to the saddle on my right side so it is very easy to reach down and pull one out when needed.
I also have many pre-setup trees with climbing sticks already on the tree. I use the top stick as my foot base with 2-4 screw in steps permanently in the tree (not necessary, you could bring the screw in steps with you each time) around the rest of the tree to allow for movement. I also already have hooks at the top to place bow and gear pack on so I can be up the tree and hunting very quickly with very little noise or disturbances.
It seems like you guys could really make it a simpler process if you just got you some sport climbers. Provided you have the physical ability to use them, their not for everyone. You seem to be a young fellow so you shouldn't have a problem.
