i have a 22ft slx and can reach some 3 storey houses, even some with dromer window, however on todays round i do a large 3 story house which i can't reach with the 22 as the ground in the back garden slopes away from the house. the 22slx is a great pole, its my every day pole, but i do have a 35 slx for anything it can't reach, if you plan on getting only one pole i would go for a longer one, hope this helps
