Shevchenko beat Holm and went the distance with Nunes twice in very competitive fights. Those are both big girls and she was always small for 135. At 125, she'll dominate. I must admit that I don't know shit about Montano, but if she's an actual 125er, she's probably going to get wrecked. Shevchenko is used to fighting much bigger girls and shouldn't have much of a problem at 125.
