Well I know you said you want to avoid CF but there really is no reason to. I am a heavier rider (225 lbs) and I have full confidance in my Roubaix...and I would also have it in that QS2 (though thte ZX3 has a better geometry for me.
On to advice you will probably take a little better...don't bother with the Centaur brakes...just get the Veloce unless you have some deal where the Centaur are less than Veloce.
