Well if you recently got it (obviously since it just came out), I don't have it but honestly, it sounds like you just need to practice more... You say you have problems doing the move quickly, so practice slower until you get it perfect slower, and then start speeding up. Basically, take your time - it doesn't look like you have to spend months on it, but spend like a week on it, and tell us if it's still a problem after practicing the move for an hour a day during the next week... If there's a specific grip problem that you don't want to expose, you might want to PM someone who has it. Otherwise, just practice.
