Graham I just now ordered the Manfrotto 410 geared head from B&H photo in NY, you can probably get one there in the UK. They support 11 lbs. I have three ball heads, none geared, one Linhof, a Leica and a no name piece of junk. I don't like any of them. I usually use a Bogen 3047 but the 410 geared head looks like a winner for travel use. Good luck with your choice, there are a ton of heads out there at all sorts of prices so it's not that easy.
