I do the vast majority of my spring training on a Wabi Lightening SE fixed-gear and my brevets on a Jamis Aurora Elite touring bike which is obviously set up quite differently than the Wabi.
I would ride a 200k, maybe a 300k on the Giant. 400k and longer, I'd take the Rawland. I'd probably take the Rawland on the shorter distances also to make sure everything was dialed in.
