So you like Miller's decent coverage and then an ad nauseam comparison of Iowa vs Michigan from Deace over Morehouse & Dochterman? OnIowa is likely the most listenable and objective podcast out there with AllHawkeyes a close second just based on the quality of guests they bring in.
I subscribe to 9 Iowa podcasts
Great:
On Iowa: I will listen to this one first if they all downloaded at the same time. Great sound quality and really great in depth break downs
HN: I love John's take on things and his reaction as a fan of the program. Deace can be hard to listen to but he does his homework. Deace just needs to leave his political views out of the sports talk.
Iowa Huddlecast: Anton Narinskiy gets a lot of former players on and we hear some very funny behind the scenes stories from the players point of view. Drew Tate seems to be there for name only
The rest:
Hawkeye Report. : can be great depending on the guest. But, bad sound quality, oddly timed themes, and a somewhat disparaging tone at times toward the fan base make this one hit or miss.
Hlas: simply an interview based podcast
12 Saturdays: funny, but just a couple of Iowa fans discussing games
Two-Star Hawkeye: similar to 12 Saturdays but a bit more incite but less objectivity PlannedSickDays is good
All Hawkeyes: like listening to a radio program with random callers adding
very little to the a conversation that rarely stays on topic
Black Heart Gold Podcast: very funny at times. Interviews with upcoming opponents' bloggers at times can be insightful.
All that being said, I listen to almost all of them if I have the time
