Throw,f,f,3,b2,1,1,u1 7 hits 48%
Throw near corner,b2,4,d2 6 hits 60%
prolly won't be able to get the first one very often. In theory throw ff3 throw ff3 is an infinite but not easy to pull it off.
This post has a lot of combo's most of the characters don't have very good ones but the tanya ones are alright.
