I had a $250 Retul fit. Then I started getting a lot more fit and a lot stronger. I ended up flipping my stem. The next week I removed a spacer. Two more the week after that. Eventually I had all the spacers removed and had to flip the position of the bars down to accomodate an even more aero position. It didn't affect my fit one bit but your mileage may vary. I was nervous about "screwing up" my fit as well but it ended up not being a problem at all.
