Replying to 3 swap help

How do i spin faster on 3 swaps? Ive done them both ways on a aframe with a lot of hangtime but i really want to learn them on flat rails after seeing j karsteter doing them, i spent almost all day today hucking them around on the flat rail at the mountain but to no avail, id either land front 2 and straddle the rail or id spin front 2 onto snow to the side of the rail. For reference i can front 4 most rails pretty easily but this stupid trick is not going. Any possible solutions? I have no clue how to spin faster on a rail lol
