Obviously that suggestion goes out the window if you are racing I suppose...but no one says you can't race on a endurance frame. Bigger the frame, the greater the wheel base as well which effects steering quality. If you don't like having a lot of seat post, go with a bigger frame, and a shorter stem. I don't like a lot of seat post, and I feel it is much easier to get in the drops, and stay in the drops longer with not as much seat post, and a shorter stem to boot. Some people may feel crunched up, but I find myself staying on the hoods and the drops more...which means I am able to be more aero for the majority of the ride. Stems aren't that pricey either so you can experiment, and just sell it on fleabay if it doesn't work out.
