Nice. You've been very busy! I know you like the string line but does the plane board provide any shocking insights to your mind?

Thanks

Yes two things;
With the board there is a tendancy to try and lay the clubshaft on the plane. this creates/encourages a sweep release and can screw up rhythm.

the soft board shows sweet spot plane. because at release and swivel the hossel goes below plane and puts a little dent in the board.
