I've always walked the end back to the van/reel but I still get in tangles.
Like you Jeff I did have half a tennis ball protecting my tap, but i took it off because it gets in the way.
I took Ian Giles idea of having a harness around my neck and under my arm connecting the hose end/tap to that and walking away and back to the van that way.Often picking up' bunches' of hose on the way back.
I've put posts on here several times fishing for electric reel ideas which I believe is the last obstacle in my way to having the perfect van set up.
First time I saw wfp was an internet video of Matt with his unger pole (about 14mths ago). It looked so easy, I had to start a wc biz and have one. Now look :

Just read Jon's post. Worth £500 if it works.(I'm hoping Matt and jeff will come up with a convert idea, and for this very selfish reason the sooner they both get vanned up the better.)
