Read through all two decades ago. Two telling things:
* he came right back into writing the WON almost instantly
* he spent a significant amount of time covering the WWE in 1984-85, more than any single promotion
I think if one looks at the 1986-89 WON's where he finally settled into the weekly format and coverage pattern that he largely still follows today with minor tweaks, the coverage of the WWF was significant.
Did he enjoy the quality of WWF work? Not a ton of it. But then again, not a lot of hardcores did... and that wasn't really the influence of Dave. They all preferred what they grew up on, and generally saw the WWF as weaker / less entertaining / less fun. There are some WWF backers, but they were a smaller, less vocal group of writer-fans in the Letters Section.

From reading the 84-87 ones, I was always way more frustrated with the AWA coverage while watching the set.
