Thanks mate, but from what I have read the Kranzbuhler bats still have fairly big toes and shoulders as the willow is so light.
I'm interested in what people think is the minimum with a standard piece of willow, to then allow the weight to be put in the middle. For example my red ink x2 has a 20mm toe and 14 shoulder (at the edge), which allowed me a 44mm edge, but I think that the toe could be a couple of mm lower, not sure on the shoulder.
I know it's not an exact thing as the shape from the toe up can be massively different, but does anyone have specs lower than this and if so has the bat survived ok, or was it vulnerable to toe damage?
