It's not about being tight, I think it's about what suits you best.
I broke 3 sections on my old Extreme 25', but I had a spare so borrowed sections off of that.
In the end I bought the latest Extreme 22' and it is more durable than the old ones...just.
I also have an SLX 22 which I stripped down to an 18' but unfortunately I am a big girls blouse, with dodgy elbows so I don't use it.
However...I am much more careful. Pollen gets cleaned by tilting the brush on its side and gently rubbing the glass with the plastic stock of the brush (make sure the glass is wet), I am much more careful with open windows and gently try them or if they don't close (i'll clean them while they are open, or not at all). And generally I don't throw the pole about. So far so good, we'll see how it goes.
