Thanks Ed. Yes my left hand certainly does need some work - jerky movements and raising my fingers too far above the fret board.
Regarding the right hand, I think the key is to keep the movement of the hand to a minimum so that the strings fall naturally into the right place.
Sorry for any confusion from my previous post, I included some of Andrei's post and it may have appeared that the post was made by him.
I noticed in Andrei's demo video that his fingers are striking the stings at around 45% and he produces a nice tone. I think I stike the strings at a similar angle.
Your playing has come on a lot since I was last on the forum - so keep up the good work me 'ol mucker, your perseverance is paying off
