Roadiewill, Good choice, I have a basic SCR4 which is my winter bike, it only came with CroMo forks, but I'm not worried about that, I wanted something strong and reliable with mudguard clearance, to keep me on the road during the winter, though I just couldn't muster any enthusiasm this morning for the club run, peeing with rain and blowing a gale here.
so just did an hour on my rollers.
Not sure regarding the carbon composite question, but cannot imagine that it will have ANY significant impact on how the bike rides or handles.
Personally,with the CroMo fork, apart from a slight increase in weight ( which is a good thing in a winter trainer IME) I don't find it makes much difference.
I do notice the difference though when I get onto my best bike, and all that effort put in hauling a heavier bike uphill pays dividends!
I find my SCR4 pretty comfy, I was surprised at just how comfy in fact, the saddle, which is only a GIANT branded model is actually quite pleasant to sit on, and didn't require any bedding in at all.
You have made a pretty good choice, in time though you may consider swapping the rather sluggish Alex DA22's off, in favour of something a bit more whizzy like a mavic, which is what I did, I put some Aksium race wheels on, and noticed an immediate difference.
