i agree with moggy...palms down is a huge key... also hold one hand the dyneema wish bone and pull until you can get both hands on either rubbers... i used to grab one rubber pull until i could reach the other rubber and skew the rubbers(one side was longer than the other) ment i shot skew... long arms help..lol
