I have only climbed with a traditional system so far, but I like to diversify. I decided to try and rig up using an eye n eye tail with the pulley. I used double eye pulley since thats all I have at the moment. I decided to get out and try it quick before it rained, but something here isn't right, I just don't know what. It was a major pain to advance the hitch while body thrusting. It's not that it DIDN'T work, it just didn't work well. Is it the placement of my carabiners? Instead, should I have clipped one to my saddle and through the bottom eye of the pulley,and then used another through the top eye and also clipped through the eye on my rope?
