Thanks for the suggestions. I bagged some on ebay before realising they are latex and therefore totally unsuitable for everyday use. Doh! Expect to see them for sale here soon
There's nothing wrong with tubs with latex tubes in them, they ride much better than butyl and can easily be repaired with caffelatex or simliar, so long as they have a removable valve core.
