Maybe it's better to leave a spare on the seven point, but I like leaving an even number of checkers on the outermost point and bearing one in to boot.  7/1.

Oh..and btw..the reason for dropping the embedded image into your first post, and not just the poll..was so that it wont disappear when people start posting.  I really needed to refer back to the board to check my 'ditto' remark...and it was gone  :(
