Well MMP... There are a several composites out there.. I just know the Composite-Arf is a proven company with proven products. Many of the other composite companies are basically beginning the production/distribution of composite airplanes. Give them a little time and then we'd be able to make a reasonable assessment of them.

As far as the Edge, Extra etc., it depends on what you're looking for the airplane to do. Sequence work, 3D and/or a little bit of both? Do a search on composite aircraft and I'm sure you'll come up with the information you need that answers all your questions.
