Hi Sands
The only thing i use a float for around here is to string fish off, most of the time we just chuck the fish in the boat, so i dont have to use them much but the are good for bleeding fish on.
I personaly dont like them, the cord allways get tangeled on something and they are a pain do drag around.
If you have to use one i would go for one as stream line as possable.
We may be going after some Dog tooth tuna this year so i have to get a boogie board or a few big floats with some bunge line myself
That Tommy Botha Tunny Busta rig looks like the go

But you may have opened another can of worms Remember different floats for different folks or whatever floats your boat
