if they are not the best in each lower style,then why do u say they are world's bests?and that nobody can touch them??(at least in your heart that's what u mean)
as for my combo-
if u are anywhere near top class,which has to have certain basic standards,and which only few russian fsers fullfill..
then satw-halfhtw-batw nt should be easy,or at least satw-timo-amatw/matw nt..
and can anyone of the "HARDCORE" people do that?
they can just do practicing for ahmatw,latw-alatw...
