I can't watch this cause i don't like playing my tt :). 1st of all I would say thor fc is not really effective imo (might be cause i'm only 1730 rated). I used to have a bo for classical in 4.10-4.20 in all maps, but due to seeing that it isn't very effective i changed to a slower classical.
EDIT: well ofc fishymaps might be p00nage with a fast classical ;)
