I think Taylor does a great job with Cedar tops. I own/have owned Cedar over Rosewood (GA), Mahogany (GS), and (my favorite) Walnut (GC, GA, GS). Cedar-topped Taylors never seem to get too muddy or squishy - just nice and warm with lots of overtones, but still a bit of sparkle. Taylor's "Modify-a-Model" program is now just referred to as "Standard Model Options". It's a great way to take a standard guitar model and makes some minor changes (top swaps, scale length, nut width, finish, tuners...etc.) at a reasonable cost. It is how I got my short scale 814c with a tobacco burst and no pickguard as well as my short scale 714ce with bone nut/saddle, clear pickguard, and Gotoh tuners. It's easier than going full BTO and less expensive for the same specs usually.
I would recommend playing both a GS and a GO. Cedar-topped GS's are wonderful for fingerstyle and do well with light gauge strings. It's a pretty big body and a full-sounding guitar with lots of bottom but no mid scoop - very tonally balanced high to low. I haven't tried a GO yet, but would like to.... although I suspect it might be too big for me. It's hard to go wrong with with a Mahogany/Cedar Taylor! Keep us posted on what you decide.
By the way, you don't contact Taylor directly to have a guitar built. You have to work with an authorized Taylor dealer to place your order.
