Eastmans is Wyoming-based which definitely contributes to it. On the forum side, MM is Utah-based and focuses there, HT is Montana-based and seems to focus there.
Also, Wyoming is a tough state to cover concisely in the MRS because of their management-style. A state like Utah is easy to cover (Henry's, Pauns, San Juan for deer... Beaver, Kaiparowitz, San Juan for elk... done).
Wyoming doesn't really have clear winners for most species which requires a much more in-depth review to understand where to apply. Many units have the capability to produce trophy animals every year, but those same units also have the capability of being a very tough hunt every year. Also, with the recent weather patterns the state is in a bit of a transition which requires more research. Just my thoughts.
