Dunno which way you're spinning, but make sure to look where you're spinning with your head. Your body should follow if you're setting the spin off of the rail right.
Either way, for setting your spin you'll need to press down with your toe on the rail to push yourself into the spin.
For a blind 2, it looks like a much less exaggerated version of this:

For a front 2, it'll be your trailing toe that does the work. Once you set the spin that way, POP off the rail. Seriously, jump and you'll have a way better time. Then, lead the spin with your head - your body should follow. This means for blind 2, you're trying to crane your neck to spot your landing downhill. For front 2, you'll be trying to look back up at the rail. Tuck your knees up a bit, and when the time comes, deploy that landing gear with confidence.
For swaps, these exact same tips apply. All I did to learn them (both front and back variants) was start my 2 out way early so I was juuuust barely catching the end of the rail at the 180 point. Then start them earlier and earlier on the rail, and bam, u swappin' now boi.
