Thanks for the kind words. Did you end up going with the coaching lessons? I ask because just last week, I met up with my old coach from ~30 years ago...the guy who taught me to play. Of course I grabbed the opportunity to ask him to fix my serve... Took him less than 5 minutes to make some corrections to my serve (wasn't projecting my hitting shoulder out and up, and keeping my weight back). Things which have been suggested/corrected here on my serve thread, but sometimes it really does take an on court lesson to drive the point home.
He was kind enough not to say "WTF happened to your serve?"
