I used to use my 6.3 to 1 reels and attempt to reel slower with crankbaits. I've now found that when I'm using my Fritts combo, I am getting far more strikes and hookups with the glass rod and the 4.3 to 1 reel.
I like the fact that the bait stays in the strike zone longer. Also, I can certainly switch to a rod/reel combo with a 6.3 to 1 retrieve, any time I feel that it's necessary. No matter how slow you turn the 6.3 reel, it still is going to bring in 33% more line per turn of the handle than a 4.3 reel.
Just something to think about.
Different strokes, for different folks. BTW, I believe that Pfluegers, are made in the same factory with virtually the same parts, as the BPS reels. I know a number of anglers in my club, that swear by them.
