I tuck...
Find a jump....speedcheck it. If you don't want to have to really huck it....a 25 footer is perfect. Commit to the backflip before you hit the jump.
Drop in...tell yourself "I'm going to backflip." This will get you in the mentality for throwing it and make sure you don't bail on it halfway through. Pop off the lip, go with the momentum of the kicker while throwing your head back. Then tuck...enjoy the ride, spot your landing...and STOMP.
