I was thinking of saving $30, getting the B, and upgrading the bearings with
the money I save.

Are the bearings the same in these 2 reels?

Is the BSF just so much better that I should get it instead?
I have owned a 200B and liked it a lot.

Current baitcasters I own:
Calcutta 400 w/ceramic bearings
Calcutta Conquest 200
Calcutta 250 w/ceramic bearings
Scorpion 1000
Scorpion 1000
