for 270 offs, it is much easier to do a unatty 270 off to fakie, if you slide right foot forward, because that way you can spot your landing the whole time, and you can just float off the rail, and there stylie as shit... if your going left foot forward its way easier cause you can spin your natural way and land with the landing in your vision the whole time...
for 270 ons, the best thing to do is try em on boxes and small rails first because nutting can happen really fast when your just learning... or you can do em disaster on small single kinks just airing 360's over the whole, thing, then slowing it down.... but what you want to do FIRST AND foremost, is make sure your watching the whole rail as your doing your spin on, never lose sight of that mother.... when you spin always have your eyes on it...
as you approach the rail, have you body (not feet) already a little bit initiated to the spin, so alittle torqued to the side, it looks rad and it helps alot, just make sure you spot, and land on the rail very centred and balanced..
hope she helps
