Hi Michael,
It doesn't sound to me like you have problems with this; in fact you’ll be pleased to know that it sounds very normal. I too had this issue when I first learned the move; it just happens to be one of the first milestones you must get over before proceeding with your practice.
I think the best course of action would be to ensure you have the correct grips. For this I would recommend learning the Erdnase Shift first before attempting such an advanced flourish. You can find the write-up on
page 101 of the
Erdnase "Bible". Once you are sure that you do, it will just be a matter of time before your hands ‘mould into shape’ and feel comfortable with that grip – from there it’s a simple matter of hardcore practice.
Hope this helps,
Jordan
P.S. You may also find it of interest to check out
page 9 of Dan and Dave Buck's PDF,
Five - which is actually the place where I learned the Revolution Erdnase. To be honest, before reading this description I was unable to perform the move at all - the write-up in the Twins' notes certainly gave me the courage to work on the move, and ultimately learn more advanced methods (such as Erdnase Go Round).
