Personally I like the Swim Smooth stuff. Lots to work through. I'd look for somewhere that can video you swimming and then show you what to work on.
BTW I do like TI but, for me, when I tried it I was trying to be too long and slow. Swim Smooth is more about being analytical with where you are and then what the best way forward is.
