Don't throw your backroll as fast. Do a very very very slow backroll.
Pass earlier and get more inverted.
Just to clarify I think what andy means is don't spin so fast in a horizontal plane, instead focus on spinning in a vertical plane so it seems like you spinning slower. If you get too much momentum spinning horizontally I find it hard to stop and you end up passing later.
Oh yeah and try em on both tacks. I could only really land em toeside occasionally on one tack, went the other way (even though I'm crap on my other tack) and I found it worked better.
