I think Lara is the less talked about, but is the best of the group.
If Solis gets in fuking shape, he could be the saviour of te HW division
Gamboa is very good and very exciting to watch, but like you said his style and shaky chin will get him KO'd sometimes, but he will KO some Mo FO's too.
About Rigodeaux I think he is talented, no doubt, but he wont be as great as they expect. He is too inactive and too within is ama style. He will be champ, but nothing special!!!!
