The main is about as interesting of a fight as you can ask for at LHW, so for me that's enough to cancel out the apprehension over how fucking boring it could be. Similar sentiments Okami/Miller, as Dan needs the step up and Okami really needs to keep sharp against someone who can actually do something against him. I don't feel Sherk/Edgar, as it'll probably be another example of good grapplers putting on a decent boxing match with no hope of the fight actually ending early (probably the most valid criticism of UFC-style MMA at the moment). Irvin/McFedries is fun but definitely not main card material, and Serra/Hughes is all kinds of irrelevant while still possibly mind-nimbingly boring.
Larson//Wilson and either Nover, Gusmao or Yoshida on the main card would be much more appealing, IMO.
