Is this your first grab? I would try something easier if it is like an indy grab. Just keep the rope in tight and make sure you bring your knees up to grab...not just bend over at the waist. Coming in with a knees bent edge with help you pop up a little more instead of going out as much. Just focus on your pop FIRST and then worry about grabbing he board. Keeping the handle in tight to your hips will make it much, much easier.
probably gonna get yourself a melan or nosenchaly grab no matter what you call it unless you shifty and bone out your back leg, which would be amazing for anyone to do as a first grab. a method is a commonly mislabeled trick. either way, good luck.
here is a trick tip on it, showing a proper method:
Method is a tough grab/move. I can poke indys, tails, stalefish, and half decent melans, but I can't quite get the feel of the method down. When I do them it looks more like I'm trying some sort of sissy raley
