nice to see you again.
you need to come back to san diego so that we can finish our US/Canada davis cup doubles tie. We finished at 5-5 as i recall.
Here's something you might want to try. A good tip I got years ago for the volley. Instead of just 'hitting' the volley try to get the feel of letting the ball push the racquet head back on contact. Keep the wrist firm but not tight and let the ball push the racquet head back.
Just try it. You'll see the improved feel and control when you do this.
You don't want a solid wall feeling for the volley. You want more of a 'pouchy' feel.
