Huge Backroll!!!!!!!!!!!!!!!1

I rode all summer with this French guy who seemed to go massive with his backroll! Not that im jellious or anything (LIE) but thought i would check out a few things to improve my lame backroll!!!

AS you throw it should you be totally leaning on the line??? If not how much tension should you have on the line???

Do you throw your board 90 degrees to the boats path or straight infront of you as you hit the wake???

Which shoulder should you look over??? I ride Goofy

Thanks

Danny
