Just my inexperienced opinion, but if you are coming from riding a hybrid bike, my guess is you don't really know what you want in a road bike. I'd get the best fitting stock bike you can find and save the extra money for when you really know what you want. Then get the custom bike if that's what you really think you need. I can just see jumping into a custom bike right off the bat to be a waste of money.

Feel free to disagree
