I also prefer the wind to be blowing. If you are fishing a generation lake and they are not generating the wind can cause enough movement with the water to make the fish active. Just remember if throwing a bait caster readjust it for throwing into the wind otherwise you will have a huge knot to work out ( speaking from experience
) It also depends on the size boat you have. I am comfortable in 20 MPH wind but I also have a 21 ft glass boat that handles rough water well. Also remember if you are fishing Hickory there are enough coves bays and even the channels that depending on the wind direction will keep you out of the worst of it and off the main channel
