I took a very different approach which I am very happy with.
I use 30 metres of pole hose spliced into about 60/70 metres of microbore. This means that for the majority of my jobs I am just flicking very light hose around and reeling in very light hose too.
If I know I need a lot to get to the far end of a property I can walk to a "pinch" point, drag and loop up lots of hose and carry it to the far point. (lighter to carry than loops of microbore)
Haven't sprung a leak in a year now and very pleased. Also when I replace it I only buy 30 metres and hose joiners as the microbore rarely gets pulled out and gets little wear and tear.
It's the green pole hose from Gardiners - (THEY DO NOT GUARANTEE IT AS A MAIN REEL HOSE) - and its no cheaper than microbore but it works very well for me.
