For me this depends on when it happens...
If it were to happen tomorrow I'd vote 4-2 Waters, but by the end of the year Thomas will be taking this IMO.
Since moving and starting to train at Cambridge with Dan and the Minotaurs I have been excited to see good, intelligent, hard training again! It's been a few years but with the club improving all the time and see Dan Thomas and myself moving up a level or two this year.
