Hi! I am upgrading from my 12yr old Giant TCR Once and looking at these models. Mostly a mtb'er but doing annual Argus and DC therefore needs something light and comfortable but definitely not high end stuff (I also need something that will again last 7-10yrs...upgraditis only applicable in mtb'ing). Shimano 105 or equiv is the minimum requirement. Issues: 1. Value 2. Comfort vs Racing geometry (or is it more about a proper set-up) 3. Price: <R20000 (I can get these models at between R16500-19000 for 2012/13 models) 4. Other bikes Thanks!
