Very good points, thank you.
I have been using two long cables to/from effects loop and the wireless receiver at the amp. I suppose I was a bit irked having gone wireless to still have these blimmin' great loops of cable to lug around, and then cluttering the stage (pub floor). Instead I am looking at the possibility of a clean set up. As you say it's more to go wrong, and I'll still carry the cables as a 'just in case' so really it does seem a bit pointless.
But it gives me something to think about while twiddling my thumbs in this gig free world, and who knows, one day I might get to try it.
