Flyweight has been putting together some nice fights and they usually fly under the radar. It's one of the most stacked divisions and everybody seems eager to face each other. The one negative is that the division doesn't get much tv time.
I love 140-160 as well though especially WW & MW. Those divisions are full of so much history and great matchups.
Personally light heavyweight right now. Big, strong guys with plenty of speed to boot is a scary and exciting weight class.
As of a few days ago, LHW can go fvck itself.
Stevenson vs. Kovalev was the match up to look forward to this year.
Flyweight without a doubt.

And unlike the most other weight classes most of these guys have faced or will face each other in the near future.
