basic grinds I can think of right now: frontside, backside, royal, unity, savannah, farv, soul, mizou, sweatstance, acid, fishbrain, makio, fastslide, torques, umm i'm sure i'm missing some. then you can do all of those fakie, switch, negative, true, topside, (might have missed one of those), and lots of combos of those all for doing just a single grind. and there's spins on and off too. then switchup to your hearts content.
