I use Planet X Jet Pro clinchers. they\'re a cross between convential clinchers and tubulars, in that they fit clincher rims, but have no inner tube. They are highly puncture resistant (I also did Blackpool!) and can be inflated to a ridiculous 160Psi. They also come with some gunk which further helps puncture resistance.
The down-side is that they\'re £30 each (more expensive versions are available!!), and if it does puncture (generally only when a side wall rips apparently) you need to carry a spare tyre rather than just a tube. THey\'re also a real bugger to fit - I was advised of very sore hands and lots of swearing after they arrived in the post.
Mine survived Blackpool and, more impressively, Lanzarote, but the gunk blocked the valve on the front tyre, meaning I couldn\'t keep the pressure high enough, and it eventually blew as I careered into one of Lancashire ubiquitous deep potholes.
The back tyre, which I hav a habit of puncturing at a lightweight 13 stone, is still going strong.
Sorry to go on, hope this helps!
