I have had the 14oz. wooden handle Stiletto framer since they came out. Still love it. You have to cut about 3/4" off the bottom to fit diagonally in a systainer, but it's packable. I also have a straight claw Dalluge that I'm not properly using yet.
Last week I was fixing a lot of stud walls to a brick building with 6mmx75 pins, drilled and hand driven. I had an Estwing mash hammer handy to use. The ones over my head were just too hard with the Estwing (which is 3-4 lbs?), but the Stiletto drove them really easy. It's true that because it's lighter it travels faster, you can really get a solid swat in accurately. No less important is that it doesn't pull your pants down with the weight.
Fair enough, when I worked as a grip, the most important thing was that it wasn't heavy, not how it worked. The traditional hammer of choice is the 16oz Estwing, so this was two ounces lighter and about four inches longer and twice the size. Mine was $60 when I bought it from Amazon (shipped!)
