I would avoid pop rivets, just because I find them difficult to drill out without drifting off-centre, and the aluminium formers are thin.
Seriously Dave? You have difficulty drilling the top of an aliminium pop rivet without tracking off centre when there's a pilot hole through the rivet?
Personally, I would avoid double sided tape as should you wish to remove the running strip base from the wing, one risks damage to the paintwork. I can understand that pop rivets might offend the purist but they are easy to use, cheap, easy to remove and out of sight so unlikely to invite any adverse comment from the purist.
