Will you be getting PC?
Nice video, shows the versatility of grinds but doesn't "wow" very much. It was an enjoyable watch, I like seeing the limits being pushed and new stuff coming out of GTA:V.
Combos are definitely next. I've seen tons of methods coming out of the game lately but I haven't seen them used in combos very much. Having a big library of methods really opens the world up for cool set ups. I've got a few ideas for combos already but will probably take a few weeks to beat the single player and get a good feel for GTA:O before I stunt seriously. At least, that's what I'm hoping 
Knowing me, I'll probably just start stunting immediately xD
Trust me, seeing all of these various grinds and slides and getting ideas is one thing, but actually finding the spots to land these combos we think of is borderline impossible. Every night I think of amazing ways to combo these things (like most stunters), and then I wake up and spend hours looking for a spot to actually land it, but I never find it.
It's easy to look at a video like this and think "wow, that nose slide would make a great combo!" but the map really doesn't favor this kind of stunting. There's loads of easy ass Thrust grinds around the place, and little gapes to Shitzu slide under (which I love) but there's almost nowhere to combo them.
