what about these things: Autosock[/url] they’re about 60 quid a pair i think and take up v little room. Look quite easy + quick to fit as well.

Not seen anyone using them mind, but they seem to get ok reviews. I’m toying with the idea of getting some just to get from my house to the main road as being self employed means if i cant get to work i dont get paid. Got stuck a few weeks ago as i couldnt get more than a few feet along the lane from my house. Seem easier + cheaper than chains and can use them on cleared bits of road (although this will probabaly wear them out fairly quickly)

Drillski, i thought it was only 20 mins for saliva to neutralise the acid attack ( trying to remember lectures about stefan curves now!!). I guess if you have eaten something like a toffee which will stick to teeth then this acid attack will go on for 20 mins after the last bit of toffee has dissolved and could significantly prolong the duration, but for general foods 2 hours seems a long time. However i may be wrong and will view any corrections as part of my CPD requirement!
