natural dirt jumps are always better...

 

yeah cuz metal ones get wet and you'll like slide all over the place and wooden ones break I'd just stick to dirt more safe and cheaper to build

 

IC well yea it was more like at freestyle jump but i think i might just stick with the dirt jumps, but what i was going to do is set it up in my yard for a snowmobile to so im not sure what im doing yet but if there are any sites that do tell you how to build some metal ones would be nice

 

i wouldnt say "natural jumps" are better

but using "natural resources" is prolly ur best bet....

dirt is just perfect for jumps...get a bunch of it and a bull dozer and you'll be set..you cant make a 15 foot wide table top with a wood ramp[img]i/expressions/face-icon-small-wink.gif[/img] and a whopps section with wood[img]i/expressions/face-icon-small-confused.gif[/img] lol

i'd say for ur own safty stick with dirt...you can get plenty of air if you put a big enough and steep enough lip on a kicker

 

here is a site with some freestyle ramps, but you have to pay for the plans. there is a free site out there somewhere. google it.

and dirt jumps have their downfalls as well. after a good day rippin' on them they start to get grooves in them or get tore up. they also are a pain to build if you don't have a dozer or a decent sized tractor or if you don't have any dirt. yeah, you can just push a pile a dirt together but that starts to leave low spots where water will collect and diggin' holes to get dirt is kinda dangerous for people who will be riding around the holes.

we were looking to build a ramp because it saves dirt, the jump is movable and usually a metal ramp won't change much on ya. but that is just my opinion and whatever you decide to go with, i hope it works out.
