Yeah that is what my head says, my current acient commuter has full guards and it is great in the wet and something like raceblades on the roubaix would work but be less than ideal.
Just something in me feels bad about buying a £2k Ali framed bike. Also the fact that is a bolt through front but not rear is a little annoying as upgrading the wheels might be a bit of a pain in the future.
The carbon diverge is just too much at the moment although it does seem like the perfect answer…
