Starfish, I'm not sure if all LBS are willing to put the same amount of effort into the right fit but mine offered.

When I bought my road bike I wasn't sure if I'd prefer the WSD or regular. I'm 5'4" with a 30" inseam so I could have went either way. They did not have a WSD in stock in my size and the factory (Trek) was behind in production and I really wanted my bike right away. They said that they would switch out any of the components if I didn't feel comfortable with the regular setup. Fortunately I loved everything about the bike and didn't need any changes, but it was nice to know if I did, they were willing to do what they could.
