Twill: You reminded me that I've got a crossfire sitting somewhere around the shop! I'm going to have to give it a try later this week. I got it w/ a trailer full of tools from somebody going out of business.
OS: I saw your post about how you showed everybody up hand nailing. My dad is known to have been one of the fastest in the area(there were a couple faster that he knew of), and he still says once in a while that hand nailing is about the same speed at the end of the day, it's just easier. He still won't agree to try using straight cap nails to see how fast the felt goes down, though. A few years ago he bet $100 that nobody could use a nail gun as fast as he could hand drive them. He lost obviously, but not by too much. You guys w/ the extreme hand banging skills impress me though, because I've always had a gun in my hand for anything more than repairs. I like my fingernails, too.
