I've got them clipped to a long sling that's looped round 2 beams in the loft and then hanging down through the loft trap-door. Means I can just unclip them and close the loft when I'm done (and the landlords visit). Where do these hanging fingerboards come from, or is it a DIY job?
..... assisted one-armers etc, but you can't really do much of that with rock rings...
