Not positive but I think what Bud is telling you is that the TFI isn't the best choice if you're doing certain cams.
Yes I see I sort of misinterpreted that thought he was saying I would need one, after checking the site and reading the info on selecting a cam I decided to go with as suggested earlier a 21 or 26 grind and Im leaning heavily toward the 26 grind a low to mid range cam, Hopefully the dobeck TFI would work well with this cam, otherwise I have to rethink this whole adventure, and truthfully my brain is starting to hurt!!
