Thanks Sumo, I gave that a slightly less than thorough read but will return to it later.
A fair summary would seem to be that there is very little weight difference between tubed and tubeless, but I'm only giving up about 2 Watts of rolling resistance on the 'fast' tyres I normally use (I don't care about my winter tyres as I convince myself they add extra training).
Yeah that sounds about right. The main thing is with tubeless you just don't get pinhole punctures, it takes a proper slash to get through. So you can ride nice, light racing tyres without worryingly about stopping at the side of an A road in 3 degree rain changing a tube.
