It looks good, but from experience, I think Unger poles go better with a back pack.
They're way lighter that fibre-glass too, but the beauty of them is, is that the hose is on the outside of the pole, giving you extra reach; therefore less moves of the backpack.
I also recommend you get one of those collapsable sack trucks to put your backpack on; it needs to have holes in the foot, so you can get at the button at the base of the back pack. I picked mine up for £20 and hacksawed a wider hole for easier finger access.
Also, your first month with the packpack will be a pain, as you use loads of water scrubbing frames and stuff. Once you get past that, you should be able to do at least four semis on one fill (cleaning tops only).
