Now that I've become an almost respectable player in a competitive B league, I feel okay about sharing my latest instructional notes to self and will be doing so over time. Hopefully they will spare you some of the sordid trial and error moments of my past, as illustrated above.
On the right is evidence of my early attempts to hit double 16s. On the left, each page on the pile has an instructional note to self when I thought, "I got it!" only to soon learn that I didn't have it. :)
