The Ocius SUL is pretty awesome. I have flown mine indoors as well as outdoors and for an SUL, it tricks pretty good. Roll-ups are fairly difficult as are flic-flacs, but all other rotational tricks are pretty good, 540, slot, axle's, lazy's, fades - all pretty easy to get and they look very good.
I haven't flown the Aura SUL yet, but the Aura UL is a pretty phenomonal piece of craftwork and will be in my kite bag very soon (as soon as I figure out the colorizor).
You were doing a fine job of flying out on the beach at kp with it
