DIY Cam Reslinging

I looked through previous forums, but couldn't find an answer to this question:

What are the pros/cons to using a short, doubled runner to resling my cams (much in the same way as one might make a quickdraw using a runner and two biners)?

I figured I could do the same thing, only instead of two biners, I would have a biner on one end the the stem of my metolius cam on the other end. I wouldn't be girth-hitching, as I understand this would reduce the strength of my runner.

Thoughts?

I've done it without undue worry. Kinda bulky. I put rubber bands on the doubled webbing to keep it a bit neater.
