After getting my first "katagatame" last night in sparring, I think I've got some conception of my game from the mount.
Basically, it is to alternate between choke options and armbar options. Both the katagatame and the gi/collar choke are nice compliments to the armbar. Last night I was very focused on doing the katagatame correctly, but I'm sure that while I was working to get the arm over and across his face and neck, I could have far more easily just stepped over his head and applied the armbar.
The next trick, of course, is to develop a side control game and a guard game. I'll worry about half guard and rear mount/back control after that. But I do think I've got a set of techniques that I can use to effectively fight from the top.
