Hope it all works out for you mate, i have the same problem net sessions just arent enough as i work away a lot so when i get back to play it all goes to pot, poor foot movement, no head movement and so on, i did a net session with procricketer1982 and i felt really good after as i actually got some proper net time, so hope it works out for you, as for me i'm planning to meet up with Gary Palmer for a intensive training session when i get back and can't wait to get some big time in the nets just hope i don't embarass myself to much as i'm desperate to start playing some big innings.
all the best mate and lets know how you get on
