well the girlfriend just bought some 166 foils today - first impressions are pretty good.. love the trend towards fat twins. the 170+ have an 86 waist and the 166 has an 83 waist..
here are some pics of the new 'spaceframe' and some size pics to compare to a fujative and seth pistol - as you can see it is somewhere in between the two. still dunno if it's a wood core, but the edges look nice and beefy.
will try to take 'em for a spin and post a more detailed review...
