I am basically doing the same.... just a couple questions.
1. What type of screw link are you using?
Amazon.com : PETZL GO screw link 7mm : Locking Carabiners : Sports & Outdoors
www.amazon.com
2. Do you have any problems pulling it down once you get on ground? I use the rope i pull my bow up with and clip to girth hitch so when i get down i can pull it down but it can be tough to pull down and scared it will get stuck.
I don't have issues, I hook my pull up rope to the tag end of the rope not the loop/screw link. Basically I end up pulling the tag end of my rappel rope through the screw link. Slides super easy and many times the rope fall down the tree after you get it started.
3. What type if pack are you carrying your gear in with and are you wearing your saddle in?
I will be going back and forth between a preadator pack with pouches on the saddle or a badlands reaper. All day sits the badlands will get the nod when I will need more water and some grub.
4. Platform or ROS?
Platform for now but thinking of giving a ROS a shot if I decide to pull the trigger on some. I like to sit and a lot of sitters have commented that they prefer ROS.
