I carry most of my "dental floss" single length slings as tripled up "trad draws." I can get them off my harness with either hand, & extend them single handed.

I carry some over my shoulder...I need to have my right hand free to get them off.

I carry a double length over the same shoulder, doubled in such a way (with a biner) that I can get it off over my head, or unclip the biner & remove it even if the right hand is locked up.

I figure that if I'm in a position where I can't free up a hand to extend the slings, I'll put up with a less than optimum length.

The extra biners? Depends on how you look at the total system of how you rack & place your gear.

Bill for a 4' sling you should just clip both ends together with a biner so you just unclip the biner and pull it out.. nothing over the head.

personally every cam gets a racking biner and all my slings are in draw form. Makes re-racking easier, faster. at the moment i rack on a sling and keep the draws on both sides of my harness. i tried over the shoulder and i don't like it.

To rack a sling on only one 'biner, clip one end of the sling to the 'biner, put your finger through the loop and twist a few times until the sling starts to wind up like a balsa wood airplane's rubber band. Then clip the end where you have your finger to the biner also. This will twist up and make a neat braid hanging from the 'biner.

probably.. i missed the 'or' why you'd pull it over your head when you can unclip threw me off.

Normally I throw my two foot slings over my shoulder. However there are times that having to switch hands on a hold so I can get the sling off my shoulder is a major PIA. So what other options exist to stack the slings on your harness or gear sling? Obviously I could turn all the slings into trad draws, but that requires extra wasted biners. I have tried stacking them in two one foot loops back on the single biner that comes attached with the sling. That works okay, but I think a better option exists. So what do you all do?

Let me make sure I understand. You have 2' runners, each with a single biner, right? If so, a couple ideas. Tie them up in slip knots or short daisy chains and rack them on your harness. Then you could just clip to your protection and yank the knots out. Alternatively, you could clip one end of each runner to its biner, twist the hell out of it, and then rack it on your harness. Clip, untwist, clip.

Edit: Just tossing out ideas. Personally, I prefer "trad draws."

I do that with my 4' and spectra cordolette. to do that with every shoulder sling is a major time and cleaning issues. also more of a pain in the ass while using it too. and you need a pile of spare biners for passive stuff

Why do you need to switch hands to get off an over-the-shoulder sling?

Say I'm in a stance where my left hand is in a finger-crack, (my shoulder-slings go over my left shoulder) and I'm protecting at chest-height with a cam, and I want to extend the cam quickly. I plug the cam with my right hand, pull one of my shoulder-runners over my head so it's hanging on my left arm. I clip the runner to the cam using the cam's biner, and clip the runner to the rope using the runner's biner. Now the piece is extended and clipped, and when I climb on, I just need to slip my left arm out of the runner.

I carry a mix of tripled draws on my harness and single-length slings with single biners over-the-shoulder. If I need to extend cams, I'm faster with the shoulder-slings, they're already extended. For any pro that isn't racked on its own biner, I use a draw (which already has two 'biners).

For runners I want to rack on my harness with a single biner, I double the runner, clip it, put a twist or two in the doubled loop, then clip that. That stays fairly well together and is pretty easy to un-do one-handed, but not as easy as a regular tripled draw. I use this method for longer runners, as I tend to have more than enough 60cm runners elsewhere.

Say you're in a non-vertical crack area. You're left hand is on a hold and you're protecting out to the right. Now the sling over your left arm won't reach to the pro until it's removed.
