The range session was fine, then I hit some more balls prior to playing in the Sunday stableford at my club and only one got away to the right. But when I played, I hit some of the most amazing hooks I've ever seen and had to aim way right to have a chance of ending up in the fairway!
I corrected it quite well by putting the ball back in my stance, but everything was either a draw or a hook.
I'm not admitting defeat yet though, a few more range session with some grip-weakening experiments and it will be fine, I hope.
