I was going to bet on Pianeta - but after seeing the odds I decided against it: for 1 on Pianeta you get 1.03.
I would not do it. Pianeta looked pretty good in his last fights and already fought some guys who were unbeaten/had good winning records with around 20 fights while the Duhaupas-guy has mostly been fighting against boxers with losing records.
Pianeta is a decent prospect. Duhaupas has only fought 4 fights against fighters with a positive record. What I've seen of Duhaupas looked crap, he is no good.
