Spruce,
My next project is the Gangster which is an 11 meter fishing pole (as opposed to the 8 meter Zensorflex); I'm not sure how long a pole this will provide, but I'm hoping it's long enough to do 3 story work.
As with regards to getting used to modular, rather than telescopic; I believe you used to use Unger Teles; they were rotten poles at times to adjust the height; or even worse, when you just wanted to ground floor work, after removing the thin inner pole, it could be a right bugger trying to get it back into the main poles.
With the DIY pole, I love the way I can just 'pop off or on' a section in a fraction of a second; no effort. Unwanted sections you just lean against a wall, or place on top of a hedge; or similar.
When moving with the pole I either keep the whole thing assembled, or if I've an obstacle in the way, I just half the pole into two peices. It's easy.
Just make sure you don't leave a section anywhere, when you're finished!
