I think it's all been said, delta 400 doesn't have the resolution of tmy-2, and if you don't have any specific reasons, might as well to for what's cheaper.
If like to hear your thoughts about why you want a straight curve for gloomy winter skies. Are you prepared to do a lot of burning the skies in? Because IMHO that's the main thing with straight lines, they give you lots of material for dodging and burning, but you have to dodge and burn more than with an s-curve or you get the flat looking mid tones that some complain about with the designer grain films. Because the very highlights and deep shadows simply end up further away from the mid tones on the curve, and to get them all on paper without much d&b will require a softer grade, compared to a film with an s-curve.
I think (no densitomer, just theory and casual observation) I can bend the curve down in the highlights with dilute developer and reduced agitation though, so these films are very flexible.
