I'm not happy with Final Cut Pro (X). What are my options?
If you're not impressed with X then I'd suggest going back to version 7. Learning your way around a new program will be a pain in the arse. 

I'm not sure how professionally you work but if you can be bothered, Avid is a great program once you get to know it. 

Otherwise, man, I'd probably just get used to FCPX.
