100% agreed re: Robertson screws and screwdrivers. When I first went to Canada I cursed them, not having the tools to deal with them, a quick visit to Canadian Tire and I was a convert. Love the picture, but those pants could be dangerous if you dropped the ballast itself [Linked Image]

On tips to reduce the likelyhood of dropping screws, the gum tip does work really well, but gets a little fiddly after the 45th screw.

I have had a lot of success for certain sizes of screw only, using a piece of soft rubber hose over the screwdriver, flexible enough to stick the screwhead into, but easy enough to pull off [Linked Image] Soft sheathing from some types of cords might also work.
