Beasty, get a loopie as well, great for blocks. I have a few and they are great when butt hitching chunks, ya can just loosen a bit and slide it down with out taking out the block. Knotless is alot faster in the ground. Ya can tie a bowline pretty quick so not a ton of time saved there, but on the ground its a big diff. I use the red slings alot, that hold the biner out and away from the girth, making access to the biner much easier for the groundie. Gets back up to me 10 times faster, and when it does get up to me, I usually have another set up already.....ready to go. Just clip in and pull tight on the porty. Makes it easy to go small and fast. Keeping the pieces not to big for the groundies so they can get it out with out saws or bear wrestling.
