Thanks to those who took the time to reply..
I bought a pair of Scott’s from Suttos last night at the tire changing event.. Got a great deal and Mal, Mal 5.1 and TB went through in minute detail what I thought I might want 
I ended up with a Non Sweat, Anti Fog version and also was advised to buy a pair of dual lens.. Oh and they will allow me to wear eye crutches without any hassles..
TB guarantees no fog.. :ohmy:
Cheers…
