that's up to your preference , some people like low gear ratios , some people like high gear ratios . my preference is in the middle , i like a 6.4:1 gear ratio which allows you to go slow but also burn the bait fast . unless your throwing deep diving baits (20-25+) you should be fine with any gear ratio . people choose low gear ratio for ease of very resistant baits .
btw, the BB1 pro is a reel i'm gonna get soon , can't wait !!! also gonna get the BB2 pro wide spool for my swimbait rod !!
