It was Wimberley who started the revival in the late 1970s. Also Hutchings used regular mildly acidic Kodak fixers. In any case it doesn’t matter. If you like TF-4 there is no reason not to use it. As long as there is sufficient rinsing/stopping between development and fixation alkaline fixers are perfectly good. The more alkaline, the stronger the ammonia odour tends to be so buffering to a mildly alkaline pH is preferable. TF-4 is fine.
