Re: What line for float tubing?
I use three different options for my stillwater fishing from my pontoon (I graduated to pontoons as my girth expanded...). First, for shallower applications, I'll always defer to my floater and adjust my leader length. Next, I use a Intermediate, clear sink-tip/floater for most applications up to 10 feet of water depth. Last, I use type 4-6 sinking line with a short leader for fishing on the bottom in depths over 10 feet.
Hope this helps.
I fish, therefore I am - but I gotta go to work first..."piscari ergo sum"
