Here are some fighters that that I think fit the bill... well mostly:
Saiyok Pumpanmuang maybe... though a little more of a brawler than Yod.
Chokprecha kor sakooncher will clinch from time to time.
Veeraphol Sahaprom dosent have the same power on his left kick that yod does.
Samransak Muangsurin a brawler had a powerful left kick though.
none of these guys have the calmness that yod has(maybe Veeraphol). Yodsanklai just had a very relaxed way of fighting with devastating power, and good finishing ability. Yod wasnt really a brawler, very composed he didnt waste punches or kicks, everyone of his strikes purpose was to break you down or knock you out. Mean intentions.
one of my favourite fighters. I dont think their is anyone quite like Yodsanklai.
Good news, Yod has a fight coming up against Khem Sitsongpeenong in December should be a good one.
