There are so many screws in that rig; I'll be hunting around for days! No really, the extension is pre-cut and then re-attached with softwood tabs. When the time comes, I'll split them off with a chisel... and away we go!

I like the idea of hex (or square drive) screws though; they definately hold to the tool better. I picked up a short ratcheting screw driver from HD for $7.00. It's a China Special but it will pull me through most of the close quarters screw removal... I hope.
