Lesson - return of serve and punch volleys

I went to our club pro for his help improving my game. I had already taken one lesson from him in the fall, specifically on my return of serve and it was money well spent. He got me moving forward, turning my shoulders to step into the ball and how to take it on the rise.   My return is still not perfect... but it went from pathetic to solid. I'm still working on the timing, but when it's really 'on' it has become a good weapon for me.
   For this lesson, I started by asking him what he thought my strengths and weaknesses were, and we got right into the obvious  We decided to start work on deep backhands.. went through the mechanics and my 'twist' motion.  It seems like I really just needs time rallying and on a ball machine reinforcing the 'good' mechanics.    Next, since I play more doubles we decided to spend time working on volleys.  This was much more enlightening.  I told him that I want to try  hitting more angles off my volleys, not to mention keeping it out of the net/hitting wide which I do a lot.  He pointed out that I have a swing, and racket head drop in my volley (both of which screws things up) so we worked on punching the ball more, using my legs while moving forward.   

He said part of my problem is I'm not closing the net enough, but especially to hit good angle volleys. We worked on split.. hit, move forward, split hit, move forward... punching the ball using footwork, not a swing.  Sometimes I find in a doubles match that I have to backup a bit and reset on a long point.. but the idea is there and it seems to be all about the feet and shoulder turn.    I tried it more last night and cut off some shots for nice angle winners... still made mistakes but it seems like I've already I added a good weapon to my game.

He also said that I'm not aggressive enough at the net... especially for mixed doubles.  I sometimes worry about not reacting quickly enough by playing to close, or getting lobbed but he said i'm quick enough to deal with close shots or run down a deep lobs.. and my overhead can take care of most lobs anyhow.

We played a game called 'belt notch' where 2 guys start at the service line and the goal is to move towards the net and hit each other.  You win the point only that way.... he says it really makes for quick hands. Doug won that 1-0.

I've also learned a trick about hitting short angles on a ground stroke.. you have to hit topspin, but on the outside of the ball. (same idea as hitting a slice approach not only under the ball but on the outside of it).  Granted, you have to have the opportunity to hit this shot at the right time, but it works well.  Overall My return from the forehand side has been wicked in doubles.  Against some people, and on some days not so much but overall it is improving... and whatever i'm doing, I find constant self improvement the most rewarding.
