I looked at many different hoods for the truck, most all were fiberglass, I decided to go with the SRT-10 hood.
About 10 years ago I put an aftermarket fiberglass hood on my sportscar, after a couple years it became a little warped, then a few cracks could be seen (kind of fine lines were visible well away from the hinges or areas of stress). I had a couple choices at that time, one - have it repaired, or two - replace it. The repair bill estimate was more costly than replacement, I chose to replace it with a metal aftermarket hood.
Just some food for thought, not everyone will have the same experience with things. I have a friend who has a suncoast hood, has had it for a year, it looks good so far.
