I have been trying float fishing a little bit. I have read some articles on line re float types and sizes. What's the advantage of using the lightest float possible? I find it hard to see how a few grams would make much diff for the size of bows normally found in rivers. If it was for panfish----perch, crappies, etc----I'd understand it. I would think that a 'bow size' fish that's biting so lightly that it won't drag hard enough to sink a float less than 10g, say, would be biting so lightly as to be virtually impossible to hook.
What do you experience float fishers have to say about that? i.e Does size matter?
I didn't find the right solution from the Internet.
