Who are the best fighters for a collector to get an autograph from? Factor's include availability, kindness towards fans, non-personalized autos.
Least best? I've heard bad things about cro cop
Urijah faber and Tito Ortiz super cool and always sign. 
Wanderlia silva too...
valentijn fought like complete garbage in his last fight He set the bar really low for his brother who barely surpassed his performance.
