Ultimately, I think Tomoki will be the best of the brothers. Koki reminds me of Steven Luevano with a little more pop. Fine fighter, but never will be a true top guy.
"First time we fought, Koki was very rude but fought with fire. This 2nd time, he was more polite but fought with less fire". Actually, my mistake, I thought it was Koki he said this about.
I don't know... there was a lotta hype about Tomoki, then I saw a couple of his fights... he has a looooong way to go to reach even Koki's level.
