So I've started a couple of theoretical discussions on this forum about mechanics, etc. Having gone to my first few Masters classes now and having received pointers from coaches, let me just say their pointers are way more valuable than my asking theoretical questions--although I appreciate those who were willing to discuss the questions, who helped as much as one can. Folks on the forum gently suggested the best option was for me to seek out a coach or submit a video, and I write simply to confirm the wisdom of that advice! (And hats/caps off to Louisville and Nashville Masters groups who were very welcoming to a newcomer!)
