Good topic! I'm hyped to go skate. Here's a few things I've noticed--
Flick kickflips straighter rather than off the side to get em to turn backside (backside flips, kickflip backside grinds, flip front boards etc)
Bigspin flips are just backside flips with a scoop.
Nollie heelflip: Stay square on your board, rather than pointing yourself forward like with a straight nollie, to keep it flat. I find when my feet are pointed forwards that's when my board goes for the nuts.
Frontside 360: Try not to hang the your front toes, even though it feels better to for the windup.
No-comply flip: Just do it like a no-comply shuvit. The board hitting the curb on a slight angle is what makes it flip
Front crooks: Try have minimal heel hanging off when you pop. Back foot does fuck all, just keep it out of the way.
Front nose: Make sure to tip-toe the front foot. Underturn it slightly like a front crook to make it slide better.
5-0 180 (both ways) can be done like tailslide fakies, just a prolonged 180 turn that incorporates the ledge. Once you get that down it's easy to learn to sit on them.
Switch heel grind: I've found the trick is to sit your back foot in the heel side pocket, rather than the tip of the tail, then after popping, kick your back foot behind you, the opposite side to your front foot (almost like you're doing a switch tre). It feels strange but it's the only way I've ever managed to do it.
Bigspin front board: I do it like I'm gonna do a pop shuv front crooks. It gets my front truck over the rail, and into a sloppy willy-style front board that naturally continues the rotation once I'm sliding. Because I don't do it like a bigspin, my shoulders stay straight and I get a nice front board. If i do it like a bigspin, my back truck usually hits the rail cause of too much scoop, and even if I do make it up, it's a sloppy front board.
Front board pop out fakie: Aim to pop out into a back 180 nosegrind
Kickflip over something: I've found that there's two ways to do this. You can either Jeremy Wray it by having your foot all the way on your board. This will pop it high, but it will flip much slower so you gotta tuck your knees up. This way works better if you got a bump. The other way is to late flick it. Have your foot a little further off, and flick once your ollie is starting to even out. These ones are more easy to control but are less wild.
Nollie backside heel: Speed and late flick. Flick a little more off the side than a straight nollie heel so you don't kick it into a nollie bigheel
Shuvit flip: Back foot pop shove, front foot kickflip makes it nice and poppy. If you do the flip and the shove with the front foot you end up with a little kid looking one.
Backside powerslide: Dip your head in when you're learning so that if you fuck up you'll end up doing a 180 one instead of getting pitched. This way you learn to hold on to them early on too
