I've got a set I bought from Midway about a decade ago that I keep in a shooting bag. The bits cover a lot, but I must admit they've been used more for handguns and centerfire rifles than fine old doubles. Actually they've NEVER been used on any of my doubles. The bits are pretty good, the number of them is pretty comprehensive, but they're shakey-snakey in the driver. Basically this is what prompted the interest in solid blade/handle drivers. But the Magna-tips from Brownell's look good, and I'm guessing they're solid once in the drive handle or I'm sure you guys would have mentioned it. So what about it? Here's your last chance to tell me all the aspects of what make these the best econaomical choice. Many Thanks - Marc
