Good start. Might want to think about a Ropeman 1 or a Kong Duck. You find the only way to really know what you like is to fiddle with your set up at ground level ALOT!
This is GREAT advice......^^^^ We have support poles in our basement, so when my used saddle arrived, I put it on at least once a day and went through the basic routine I saw on several online "beginner saddle" videos. Getting handy with accessing your linemans rope from a dump pouch and attaching it.......remember to lock down the gate every time. Then shifting from linemans to teather.....then back to linemans. Those reps were invaluable when testing out with a single stick at first, then hunting off a stand/stick setup to focus on just the saddle side. Finally, I set sticks, had my EDP attached by a clip to the rear or my saddle, clijmbed up, set the platform, shifted to teather, set up the tree accessory belt, hauled up my bow and was hunting.
Experienced saddle hunters relate that it is a constant process of evaluation and refinement.....and from my limitied experience....I couldn't agree more. Your prior treestand hunting experience will serve you well, so you can focus on the new skills of saddle hunting. Every time I use my saddle I learn something or customize things a bit to fit my 'system'. All the best.
