Kirkland and Angulo are both "better for the moment" type fighters, but if I were making a long-term investment, my money is easily spent on Vanes, without hesitation. Angulo and Kirkland will always be the same fighters; Vanes is getting better - to the point of becoming more complete - with each fight.
Three pretty good guys. Hopefully we can see them fight each other in the future. At this point I would go with Kirkland. I think both Kirkland and Angulo would provide too much pressure for Vanes and then I think Kirkland would beat Angulo because he has more power. I really like Angulo, but at this point I feel Kirkland would beat him.
