I'm not a coach, so I get to nag people who ought to ask for help & then foist them on the club coach for sorting out while I shoot
We're kind of back to the video thread - if you can't see it or feel it yourself then how can you make it better or know that you need to? We all develop bad habits from time to time. Routine club coaching nights would seem a reasonable compromise i.e. if you turn up on Wednesday then you will be coached if you need it, if you don't want coaching you'd better have perfect style or stay away.
