Ive done nearly two weeks with fixed reel, and I can't totally make my mind up yet if its quicker.
The trolley system is harder on the body thats a fact, lifting it in and out, and lifting 25ltr barrells of water all day gives you arms like popeye, but a strained back, and of course you constantly run out of water, when your 500 yards from the van and only have two windows left to do.
But you do have a damn load more van moves to make in a day.
On the plus side I think I can only get quicker/better at it, and I can now just carry the pole and enough hose through someones house without lifting all the gear through,which is a real pain in the ass. Also Ive stopped tradding the lowers, unless people are in and insist on it.
The van mount system I'm sure will prove best in the long run, but it just feels a bit weird at the moment
