Don't know what you have against chinos. A well fitting pair is great.
That said, 5 pocket cords are a great option in cooler weather, and I've been wearing linen quite a bit lately. That whole summer thing and all, and they've been quite wonderful. If you get yourself down to your old navy, there might be a few clearance pairs of a line they had this spring- a white 100% linen and a 55/45 light brown. They're obviously not the highest quality, but the fit is nice and so is the price.
I'm just not sure what you have against a huge category of pants made from cotton twill. If there's something you hate about chinos, odds are it's not applicable to the entire category.
