Personally, as an admirer of all the above mentioned players, the only advice I can give, is practice as much as you can.
Obviously Iris B (playing the same system as I do), is a God-Like creature. I'll never acheive her status. No attention span, me!!
Also Keith Kendrick (English and Anglo...weird!) is definitely worth a listen.
So, practice and listen to others.
