1) it's not so much the weight (which does affect it) but the leverage. The supernova carries its weight much further forward from the mount than the edelux, for that reason it is not reccomended for mounting on the guard.
2) Run dynamo wire down down tube, up seat tube. Drill top of seat post (very easy with Thomson, impossible with enve, various posts are inbetween) then drill out brooks badge, file to marry up with rack mount light holes, use conicular spacers between light and saddle, problem solved!
Thanks for the advice. Particularly on the leverage issue with the supernova. Will go down the edelux light. Looking on the Talbot sight I can see you did with the SON rear light too.
