My reel repair guy says absolutely no salt for the Calcutta's. He said he sees a lot of 400 completely ceased up that have been in the salt. I have a complete set of 700 that I used daily and love them. I have only had two problems so far and that has been with the push button release and the anti reverse bearings are starting to go out.
I don't kow about the TE and the really high end. My reel repair guy says they aren't worth the money and still the most bang for the buck is the 6500.
