i think Carbon Fiber hoods are great. I have one myself. but a word of advice; if/when you get one, either take it to a body shop to have them sand it down really good and reapply some new clearcoat. most carbon fiber hood manufacturers apply a simple "gel coat" (cheaper to manufacture in mass) which is notoriously UN-durable. will fade and haze within a year or so of sitting out in the sun.
either take it to a shop, or do it yourself. but it is a bit tricky to do it right, so if you don't have the tools necessary (eg; a sanding block, 600g, 800g, 1200g, 1500g sandpaper, a good constant supply of water, and a paint gun) then i wouldn't recommend doing it yourself. as it is easy to mess it up.
