for me this move to 2.5 hose was the best move, as we run dual wand two or three times a week.It has greatly reduced dry time and the quality of our cleaning. I have the space to do this you may not have that option. Butt 4 to the door with a 50 ft of 2.5 and a 15 ft 2.0 lead hose will give you more cfm than 2.5 all the way
PS hope you have a good glide on you wand
