ASP.NET MVC V2 Preview 1 Strongly Typed UI Helper Performance

I am sure many of you ASP.NET MVC enthusiasts have either examined, downloaded, or started to play around with the ASP.NET MVC V2 Preview 1 release. One of the many new features is the concept of Strongly Typed UI Helpers such as Html.DisplayFor() & Html.EditorFor() which take a Lambda Expression as their argument. This is a great new feature because we can now get compile time checking of our arguments and it provides the ability to easily refactor changes across our project. The old version of the Html Helpers were littered with Magic Strings that were susceptible to error and painfully resistant to change.
