First season in the saddle, winter project will be playing with rappel. I do have, never used yet, BD ATC XT, two Sterling 13.5 hollow block loops, and binders, just need rope. Plan was/is to get 9mm HTP, minimum that is supported for this ATC. Want to use the HTP as rappel line and tether, and ditch the stock tether. But all this movement to Oplux, less weight, bulk, etc. Wondering if I should sell my ATC, hollow block, and get set up with Oplux. I likely will never go higher then 20 feet, just not sure if it's worth it.
