There's lots of info on the saddlehunter.com forum. As long as you don't try to do it "on the cheap," & buy quality ropes & gear, and PRACTICE with it, over and over again, you'll be fine.
However, it's not something you want to start doing a week before the season-there is a DEFINITE learning curve associated with it. First, you have to get comfortable using your climbing system, & once that's done & you have no more butterflies in the stomach, you have to add shooting your bow to the equation. Not something that can be done in just a couple weeks, IMO.
And before you start, you need to answer a few questions, such as:
-what type of saddle do you want-single panel? double panel? hybrid? (note-I ordered 5 different saddles when I got started, & used a main beam in my basement to hang with them on & test them for comfort-that way I was able to send the ones back that didn't work for me during the "free return" period, & they didn't have any wear.)
-how will you climb-sticks? steps? SRT? DRT? 2TC? other method? (each one has its advantages & disadvantages, & those are NOT the same for every hunter.)
-do you want to rappel down at the end of the hunt, or climb back down? (rappelling is safer, IMO.)
-do you favor friction knots or mechanical devices for holding/changing your position?
Believe me, it's a DEEP rabbit hole, but IMO it's the most versatile way to hunt elevated-very few trees cannot be climbed with a saddle-based system-all it takes is PRACTICE!
The time to decide how you want to do it, & start buying and practicing with your equipment is...now!
