So basically l got my hands on a descender but its rated for 9mm and up. I do want to jump on the oplux train for rappelling after 1 stick. But since l already have a descender (grigri), l want to use what l have. And 9mm ropes from DanO is half the price of Oplux. So does anyone have any info on weight/packability/personal experience between the rope sizes? Pictures of pouch packed hanging from saddles would help, I'm thinking of carrying 35-40 ft. But any info be useful. Ill save up the $150 money for oplux and lifeguard if everyone think the ultimate rappelling combo is worth it, but $40 for 9mm ropes sound alot easier to wallet.
