Tw years ago I asked a group of three aircraft designer / builder / manufacturers which were the best fasteners to use for my Lancair cowling.  These guys were:

Carsten Sundin (of Lancair fame)
Chuck Harrison (Composites Universal in Scappoose Oregon)
Mark Bettosini (AirBoss Aerospace)

They all said the same thing, in unison.  "Skybolt Fasteners"

I have read Brent Regan's discussion of LiveLock fasteners and I'm certain that they are very good.  My recollection was that they were far more expensive than Skybolt with marginal extra "niceness" (yeah, that's a technical term...)  This is the Tridair offering, is it not?

As for Camlocs, these are the originals and will certainly do the job, but I think the Skybolts look nicer.  I did not want to save an insignificant amount of money for something that would be so readily visible to a non-aviator that was already nervous about riding in my "toy glued-together airplane".  Those types judge the workmanship solely by the appearance of the paint and interior (we all know better, right?) so I figured they would benefit from the shiny fastener...

Your mileage may vary.  All of them will work.  Read Brent's missive on the Livelocks in the archives and choose for yourself.
