Along the PAS discussion, I just try to bring tools with me that serve multiple functions and so will girth hitch a double length runner through my harness. A simple overhand knot roughly midway up allows me to clip both the end and middle to my gear loop to keep it out of the way while climbing, and then it offers me a quick and solid method of anchoring in directly. The knot in the middle allows me to extend my belay device for rapelling, and it allows me to test the device prior to leaning back and dropping into oblivion due to an oversight. Once I feel the weight be taken by the rappel device, I simply unlock the biner at the anchor, and then lock it back into my belay loop for redundancy and to simply keep the tail out of the way. I can tie directly into the anchor or master point with either the figure 8 on a bight, or a clove (I use the clove 98% of the time) and then I have the double length sling for the next pitch...or to use for the anchor. the problem with the PAS is that is is dedicated to one job only really...so it is just another thing to drag up with you...thus the sore shoulders!
Just my 2 cents!
Good job getting after it bro!
