Tips and tricks?

I wanna have tips for Grindings and just shorten crank grabs from like 5 bunny hops to 1 hop
and I can say the bench is the as same height as the wheel, Also I wanna learn 180 uni twists but I don’t know where to start?

Eli Brill’s Unicycle School videos cover those. Not that I’ve tried grinds or crankgrabs…
