Samart Payakaroon, Somrak Sor Kamsing, and Kongtoranee Payakaroon are 3 nak muays I enjoy watching box as well.
Charley Burley, Holman Williams, and Eddie Booker are 3 guys I really like, whom obviously there is little to no footage of.
And as far as rewatching old fights, all the time. More interesting and much higher level skill to be appreciated compared to the modern era, though there are still great fights (last night's FOTY) and fighters to be seen nowadays too.
