I know you love your xtremes daz, but I picked up
An 18ft facelift phoenix x a few weeks ago, 980g and stiff as brick, absolutly fantastic, short collapsed length, and just amazing clamps. I've got the 25ft for higher stuff, but for £200 I couldn't be happier.
Spending over £500 on an xtreme seems pointless if it only lasted 18 months!
I know you'll never change your mind about xtremes, but there are other amazingly good poles out there...
