i think it'll be a difficult fight anyway you put it, but IMO seeing how Calderon was able to deal with the VERY MUCH bigger Cazares, Solis has power and speed, but honestly reminds me a lot of Arce, and let's face it Calderon is the fastest and most technically skilled titleholder in the division, if he fights in spurts and moves around the ring controlling Solis from a distance he'd win the fight by most likely scores of 116-112 or something of that nature
