The 155 belt may have more prestige, but I do enjoy watching the featherweight division.
Right now 145 is the deeper division. Pettis is just trying to keep his name relevent. Seriously though, this kid needs to defend his belt at least once before he starts trying to call for superfights.
Aldo will wreck him anyway, no matter what weight they fight at.
I would love to see Aldo beat Pettis up.
