ebay is usually a good bet, you can get some used bindings pretty cheap.

I wouldn't worry about it, if the box says they're M90's it means from 80-90Kg so you're really only like 17kg under, so it'll take a little long ger to break them in.  You could go for new springs in which case i would go for the M80, but that'll take even longer to get new springs shipped.  I'd say get a friend that's heavier than you to learn how to use them with you, then yours will get broken in faster, and then you can convince them to get a pair and you'll have someone to bock with.

Is there anyway to check for sure on the springs that they are 90kgs springs?

Some times they are labled on the inside of the springs, but not always

Also where do i get new springs?

Contact whoever they were bought from, they should be able to exchange your pair or just send you new springs, more likely exchange your pair.

Are the hard to change?

I haven't done it myself but i've seen pictures of it being done and it doesn't look that hard, just a few bolts, make sure to use locktie or some similar compound when the new ones back on, don't want your springs falling off mid bounce.

I can do the 360 better than i did it in the vid its just wicked cold out, and i hadn't been on them in like a month, so i'm not getting as much height as usual, winter is annoying like that.

I'd happily volunteer Matt.

k its up here it is.

i wouldn't really call this editing more throwing it together, but its good enough for me.  The begining is some old footage from the end of the summer and then there's the new stuff from today.

if your like me you won't want to wait, i took them out for a few hours right out of the box, didn't do any significant damage, then i wrapped the springs the next day.  You can definately get away with out tire socks for a while, i did for the first few days and then i took them off for halloween, didn't know how bike tires would do on indoor flooring, and i haven't bothered to put them back on yet, but i've only been on them a few times since then, as its getting cold.  But they'res not that much wear, i'll prolly put them back on when i start going out a lot again in the spring.

shot some video, made a quick edit its rendering right now, I'm think i'm getting some better video software for xmas tomorrow so i'll prolly re-edit it some time in the next week but its just a quick version of what i can do, expect it up in a few hours.

i'd say pass on duct tape, while it will provide a good bit of protection, if you ever try to take it off it'll leave a residue behind, go with a type of cloth tape, hockey tape, friction tape, gaffer tape,  If your looking for colors do a top layer of electrical tape its available in tons of colors at most hardware stores

he was definatley doing a grind in that video, i'm gonna have to try to do some stalls like that.

Good article, still with the carbon fibre and steel springs, I dunno where these reporters keep getting told that.  This recent media blitz has been great for the sport.

its suposed to be nice out tomorrow so i'll see if i can get a quick vid of it and my other tricks

It depens on a few things, your weight, the rating of your springs, and your skill level.
I am 2 kg over the min weight of my springs, and i would consider myself moderately skilled, I can jump about 4ft, which is plunty to scare me and impress anyone who sees it.
Since you already ordered Powerisers, i wouldn't bother returning them, you might not get the full 6 feet of height but they will still be tons of fun.

here's the lowdown:
Powerskips: original jumping stilt, expensive, but very very good
Powerisers: original knock-off stilts, much more affordable, but lower quality, but its what most of us have and were all happy with them
PoweriZers/Fly Jumpers/ProJumps: Chinese knock-offs, all made in the same factory, basically the same quality and price as Powerisers, also what most of us have and were happy
7Leauges: basically upgraded Powerisers, Better bearings, more durable, slightly more expensive, generally said to be worth it by those who have them

The trick to the 360 split is that you have to pull your legs back in to finish the spin, because you spin a lot faster when you get all your mass closest to your center of gravity, so doing a split puts a lot of that mass very far away and slows down your spin a lot, i do it by kicking my legs up durring the first 180 and when its about done my legs are all the way up, but you just about stop spinning there, then you hold it for a sec, drop your legs, pull in your arms and you spin speeds up really quick to finish the 180, good luck

i've tried to do multiple things in one air, but i'm not quite quick enough for it, need to practice that and get more air, hemoves do you have any vids with multi grab airs? I haven't payed close enough attention to catch that.

i'll see if i can get a vid of the 360split, if it warms up a bit and stops raining, but snowboarding season started today so i'm not promising anything.
