LW is a VERY deep division. If you are going to include Florian you need to consider Din Thomas as well, although Din lost twice to Uno. You are also forgetting Gilbert Melendez and Ron McCullough, and Marcus Aurilio. Regardless, Melendez and Aurilio should definitely be in the top 10 in my opinion.
Also, love him or hate him, boring fights and all Rashad Evens should get some consideration in the LHW division and so should Vladimir Matyushenko.
Regardless, your list is pretty good Kempo.
