Fitch 100%. Love this matchup
Not for Penn. He should stick to 155. Fitch is a monster, hard as nails, sick conditioning and one of the toughest mofos out there.
I don't see the point of him fighting at 170 lbs.He gives away too much size as it is. He's a soft 155 and has very little chance of getting the belt in that division as long as GSP is there.
