that was my first instinct.. main card like you said...
might do it, too
other considerations:
hadzovic-taisumov +575 (i have been saying all week: i think hadzovic is gonna be competitive as hell)
stasiak-pejic +1200 (pejic a high output hometown guy and got a big reception at weighins, close fight on paper, etc)
and actually kinda like two fight pass fights:
whiteford-martins could be a slugfest and it's +1000 ("featured fight pass")
chirico-velickovic +900 - could also be competitive, likely to go the distance, two talented dudes (at least it seems like chirico is talented, we don't really know on him, at least i don't)
