The neck and weight are, as far as I can tell, identical to those on other SE 245s from this year. Before I bought a CR, I couldn't find one but I saw a bunch of SE 245s at different dealers. I think older SE 245s may have a slightly slimmer neck, or maybe it's the Indonesian "Standards" that do - but all of the Korean 245s with the signature on the headstock that I tried felt like they had the same neck to me.
The neck is pretty chunky, particularly at the headstock end. It's one of those things where the first few times I picked it up I was like, "whoa" but once you've been playing for a few minutes it's not a big deal. If you have a strong preference for very slim necks, though, this is probably not the guitar for you.
I actually think the instrument has better balance than an S2 Singlecut - although I liked the neck shape on the S2 more. It's not a light guitar but the weight hasn't been an issue for me.
