Its official, its both of us! (and I think I was being a little extreme with extreme! :blush: )
I had a lesson last night (by none other than jvt herself!

) and it was brilliant, I now have so much motivation, you won't believe!

She saw our problem immediately and this is how it went:
Drummer is stiffer on the left rein, he falls in because he finds it harder work and also has a tendancy to nap towards home!.... I am also not even, I put more weight in my right stirrup and while my right leg behaves itself, my left one is wobbly, so I am compounding the problem!
Jvt said I was too hard on myself! :blush: (aren't we all?

) The lesson went really well and without boring you with every little detail, basicaly, she said I must school little and often and that he must learn that when I say we are going somewhere that is exactly where we go! (this also has alot to do with him respecting me and having confidence in what I have asked him to do) When he falls in I should circle and he will soon learn that its easier to do whats asked first time! (But I also had him moving away from my leg so he didn't always fall in!

) He has also got to learn to maintain the same pace and I must just do nothing when he is doing the right thing and only correct him when he stops doing what I've asked!
Funnily enough, its the doing nothing that is the hardest thing of all!
I also made her ride Drummer round to see what he was like (and my Fitform lol! Which she liked!) she got him to canter left lead!

So he can do it! <_<
Thanks to everyone else who replied to this thread, I especialy like the stretching exercises and its great to hear from other people with similar problems!
