Basics are easy to get down, especially if you have rode trials you already have a stupidly good sense of balance better than you'll ever need in skating, unless your Eric Koston and you tailslide (I think so don't get pissy at me if you know) down a massive curved rail. Anyway, basics are easy to get, ollies, manuals, nose manuals, pop shove its. It's the flip tricks that are bastards, because if your upper body isn't in the right place your board doesn't want to know. Mainly with kickflips and heelflips as they're the first time you have to learn to place your body better to get the board to do what you want.
But yeah it is fun.
