Takayama has been rumoured to be doing all sorts this year...rumours of Budler, Tanaka or a move to 108
I really don't think there's a better fight for him. Becoming boss in a division like this is better than the middling opponents Ii reckon he'd be able to top off at the bigger weight.
Chanachai looks pretty good, wouldn't be shocked to see him fighting at the top level somewhere down the line.
Takayama looked lucky last time out, I have Tanaka beating him if they fight in summer as the rumours suggest.
