I like the 3/8 oz Beau Mac floats.
I used to get all caught up in having a balance system, 3/8 oz float, 1/4 oz in-line weight and 1/8 oz jig. It works just fine but a 3/8 oz float will take a hell of a lot more weight then 3/8 oz and still fish great.

This past weekend we got a nice fish out of a super fast chute. A 1/8 oz jig balanced system just won't get down fast enough to be in the zone.
We end up using baitcasters with a 3/8 oz float, 3/8 oz inline weight, 1/4 oz jig and a split on the leader. The float still fished great. Balanced, not. Bastardized, hell yes.

My best advice, experiment and see what works best for you.
