???'s about beginningSPINNING 3's

I am a heelside ninja beginner looking to progress. I have a handle hooked up in my house and feel comfortable with FS and BS handle passes. I have a history of 360s from rollerblades and snowskies (always spinning counterclockwise) and want to throw it on my wakeboard. I plan on trying HS/BS first and if that isn't working move to HS/FS. I have watched The Book on spinning but one thing I don't know is: Is there any benefit to learning 3's at a slower speed or shorter rope or should I just go out and throw it (The Book did indicate that one wake 3's may help)?
