I think I've waited long enough for all the kinks to be worked out of the F75 upgrade process. I'm not worried about the AM depth issues, as I always hunt in Disc BP mode. Most of the reports seem to have good numbers in Disc mode, so I think I will be golden. Even thought about posting up a for trade ad if anyone doesn't like their new upgraded unit and wants a non upgraded one back. Just trying to help other folks out if they're regretting the upgrade. Mine is a black SE unit, late 2012 model. It went to FT last year for a check up and they replaced the coil and gave it a clean bill of health. I think i will be set with DST & FA as long as it gets good/better numbers in Disc than i'm getting now. I'll keep y'all posted.
