I ran live reels for years. Now I haven't for years. Some convenience to live but not much really and some inconvenience to live too, like cooking your hoses if you forget to take it all off the real. My hoses last so much longer and I have them dialed at lengths that suit my most common needs. Both reels are set up for dual wand residential first. 1st hose is 100', 2nd hose is 25', and 3rd is 125' .
100' does 70% of residential and 125' covers the next 20%. Once in a while you have to throw another 125' on the ground but oh well.
I have the same section lengths on my Vacuum Reel. Each person gets 50' 2" lead hose and a 50' and 25' 2.5" hoses. All additional hoses are 50' 2" lengths.
