I have a battery disconnect switch between the battery and starter, but not a fuse. I do have a fuse in my primary wire (at the battery) that runs to my main post on the ignition switch, it's a 60amp, but low and behold, as smart as I thought this idea was, I've popped that fuse a couple times (during hot starts, pulling lots of amps) so since it's actually not necessary and everything is on it's own fuse, I saw no harm in bypassing it since I was the one who installed it in the first place. Also, other than a disconnect switch, I'm not aware of any fuse capable of pulling the amps on a #1 or #2 cable running all the way to the front, which means it's going to draw more amps during start-up, that's my experiance, good luck.
