The last two I would agree with but Buchanan and Duran were pretty well matched at the time, plus both fighters were fighting on neutral turf. Laguna - Buchanan 1 is probably a fairer shout IMO
The first post contains mostly competitive fights.. rather than tough away fights.. Not sure if these have been said but here is my recent ones Pavlik v Lockett. Jennings v Cotto.. Willie Limond v Morales
Alan Rudkin vs Fighting Harada, Tokyo Japan Alan Rudkin vs Lionel Rose, Melbourne Australia Alan Rudkin vs Ruben Olivares, Los Angeles United States.
