longboard skateboards. haha, you must've thought we are crazy...
slides....oh so much fun...
there are two types of slides, standup, and hands down.
hands down I prefer. you can either do short ones where you just tough it out and plant your hands for a quick pivot point, or you can do long drawn out slides with sliding gloves.
Basic approach to these are good leather work gloves with UHMW plastic (or a thick plastic cutting board) and then shoe-goo them, or melt them on.
After you get some sliding gloves made (or buy them) go practice some layback carves to get the feeling going. Just carve down a hill, plant your hands back side, and carve back side.
After that, I suggest a two-handed toe side slide. Get lots of speed. More speed the easier. Yeah, its pretty balls out. Go down a steep hill (this also keeps the slide moving) and begin to move a good bit of your weight onto your gloves as you turn toe side as hard as you can. Your wheels will hopefully now break into a slide. If they didn't you're now heading towards the curb or the edge of a mountain. You either:
1.) Didn't go fast enough
2.) Didn't put enough weight on
3.) Didn't turn hard enough
Anyways, you should come around so your board is perpindicular to the road. Keep looking down hill the whole time. When you are done with your slide, just kinda bring your board back around under you. That is difficult to lots of people, and I have a really hard time explaining how I do it.
After that I would suggest working on a coleman slide. They're fun.
After that you can start going and doing 720 one-footed surrenders and stuff like that.
A Word on gear:
ANY board is slideable, under right conditions. I've slid my 75mm 72a Avila's on a GS board. Anythings doable.
But, harder wheels are easier to slide. Up til a few days ago, my main sliding wheels were 78a kryptos. I finnaly switched to some proper slide wheels (sorta), and got some 96a No Skoolz.
A stiffer, shorter wheel based board is also good. A stiff board is more predictable. Shorter wheel base makes it break into a slide easier.
Trucks. Anything will do, but seismics are tough to do, and trucks like randals and holeys aren't the best, due to their ability to turn and their high CofG, but they defintately work. I like indys, 169 is a good width.
Anyways, take a look around silverfish in the 101 classes and they have some slide stuff I think.
