If your TS is good you could try a TS frontroll. Its similar to the HS tantrum with the tripping effect only a front flip instead of backflip.
You could also try a TS backroll, kind of similar to a HS backroll only the axis is a bit different and more of a straight up backflip than a cartwheel. Here is a link to an instructional:
http://www.wakeworld.com/Tricklist/TrickTip007.asp Overall I would get all your basics down including switch if possible. If all your basics are on lock (including grabbed 180's) the more difficult stuff will come really easy and fast.
BTW one of the sickest basic tricks IMHO is a HS Method FS 180 and/or a TS poked stalefish FS 180.
