Peter I tried to buy one tonight but when I got to the Paypal part it said do I want a 9", 12" or 15". It never mentioned an 11". I will be buying one of your new clampless poles but I bought a Harris 5m pole at the weekend and put an Unger end on it as a stop gap. I shall use it with that until your new pole arrives.
Basically I have been interested in your posts for a long time re: rinsing on with a mono brush, clampless etc.
What size brush do u use on houses Peter??
