I know what you're talking about dude, my friend Jake throws them on a snowboard. Kind of like a sideways-flipping spin, it looks a lot different than anything else. awesome dude.
No in fact it's a lincoln loop 260 cross grab.. that's what is it!! I did this last year at my hit.. it's a great trix with a impressive sensation of bein' lost in the air!! That's great!
considering you only spin a 360 in a dspin and then flip out of it, i would have to say this is a dspin.plus spinning during a lincoln would put you in a corked out position like in a dspin.
