First OneWheel XR Classic

Been watching these from afar for a long time, and pulled the trigger thanks to the Black Friday sales today. I'm justifying it because I've lost 151# since April 2nd, and this is what Santa decided I needed now that I won't break the damn thing. :)
Just looking for those vet tips, not to start a terrible thread of repeated info. I'll read up on a lot before it lands on my doorstep. I have some gear from bike riding, but will need a new helmet, at least. I'm genuinely excited about diving in on this.
