All I can say is practice...which may sound redundant at this point, but seriously, push them around everywhere you go....push them around like a freakin scooter....it's all about muscle memory...and to get that, you have to repeat, repeat, repeat....repetition is the key to getting good quickly...as well as assessing what you are doing wrong and correcting it, rather than wasting energy doing the same wrong technique over and over and over, which kills most people.
Can you do bw steams in circles and steer them good at this point? That will help for sure. You can PM me anytime you have questions too...
