OK book ordered, let's see if can apply myself and get some discipline into my positionals rather than the "poke and hope" I tend to use. When I get a kneeler or stander, it is more luck than judgement and so I think when one's approaching, "oh sh3t, donut coming up".
At the club there are black painted steel zero boards out to 45y, so ideal for practising on.
I'll let you know
