Southpaw v Orthodox best fights...?

[PainfromUkraine]

With both main fights yesterday being fairly disappointing and the reasoning being put down to a poor clash of styles with the sloppy southpaw v orthodox matchups, which fights throughout history have actually been real exciting wars between southpaws and orthodox fighters?

Also, in your personal opinions, what is the main reasoning when such a matchup just cannot come to life, and what is the key element of ensuring a good and watch-able fight when these styles mesh?

Name/list your fights and discuss

Two of my all time favorites:
Sweet Pea vs Black Mamba
Hagler vs Duran

Pacquiao-Marquez saga
Wright-Taylor
Any Hagler fight, especially Hearns/Leonard/Mugabi

[Foreign Soil]

Pascal has crap stamina and crap shoulders so he doesn't want to risk gassing or losing ability of an arm so he throws as few punches as possible. Bute has a mediocre chin and bad defense when he punches so he's gun shy.

Toney/Jirov
V.Klitschko/Sanders
Rahman/Sanders
Moorer/Cooper
The Great Calzaghe/Mitchell
