swimming books

I was wondering what you guys think of the books: "Fitness swimming" by Emmett Hines and "Total immersion" Terry Laughlin.Somewher I ran into an opinoin that "T.I." is just the "rephrase" version of the "F.S.", i.e. pretty much the same stuf, just put into different words.So, based on that I just ordered the "F.S."Any feedback on both the books?Any positive results from learning through the two books? Thanks.
