Does anyone have recommendations for books to use after finishing "Japanese Sentence Patterns for Effective Communication" (JSPEC)?

I'm looking for something just like JSPEC but with more advanced sentence patterns.
I really like how JSPEC has both example and practice sentences.

Thanks.

I don't have any recommendation aside from Breaking In Japanese Literature, Read Real Japanese, and retyping 昔話 from here http://hukumusume.com/douwa/pc/jap/itiran/01gatu.htm

however, I will say that I'm glad you actually spelled out your acronym. UBJG drove me crazy for the longest.

KO2001? KM2kyuu+KM1kyuu? That's been my plan so far. Still working on JSPfEC though.

Thanks for all the suggestions. Keep them coming.

I've been thinking about working on the following books.
Has anyone ever used them?
