Thanks, that's smart stuff. I actually hit a full continental kick serve, so I feel reasonably comfortable with the grip, just not on a more powerful first. I've resisted rebuilding my serve, since it's currently very effective - about 1/3 don't come back playing 4.0s - but I realize there's always room for improvement. I'm fit but not naturally athletic, so I often struggle with new mechanics.
Will still get the other couple of pics posted later this afternoon.
