cool, be interested to see how you get on with it... after getting a 2nd opinion from a mate and also talking to Craig again I've decided to try and keep the blue belts that came with the car for the moment.. a mate of mine discovered that the belts will actually lock up if you tug on them twice in quick succession.. I'm 95% sure they would lock up in the event of an emergency.. so I'm going to see if I can get through roadworthy with them and then test them on an emergency stop on the road.. if they don't work in that situation I'll swap them out somehow...
