unless yorue good at unnatty spinning itd probably be easier to spin natural slide switch (or unnatty whatever you wanna call it, actually if any one wants to fill me in on the best word for it go ahead) cause the unnaty spin could put you off balance before you even get on the rail which isnt a good start. but somehow i lucked out and can spin natural 270 and then grind natural. course now ive got to learn it the other way around...
