I fish in Central Texas, which means it is always windy. The only time it isn't windy is from about 9AM to 5PM, Monday to Friday. Other than that, it's pretty windy. I normally fish four rods; two baitcasters with spinner baits, crankbaits, 1/2 oz and above Texas rigged worms, etc...; and two spinning setups for wacky worming, drop shotting, and less than 1/2 oz Texas rigged worms.

On the baitcasters I use 12lb flourocarbon. On the spinning rigs I use 8lb mono. Lately, I feel like I have noticed that the 8lb mono blows accross the surface while I'm letting my bait fall after the cast. This makes my retrieve fairly irregular. The flourocarbon sinks, so I feel like it does not affect my retrieve. Am I crazy, or should I switch to flourocarbon for all situations, especially windy ones?

Flouro may help because like you said it does sink. But I would just up-size your weight depending on the wind.

When it's real windy I fish 1oz or bigger.

The Flourocarbon has more memory than the mono and will be more difficult to handle on the Spinning reel.

8 lb. flouro shouldnt give you too many problems on a spinning reel, IMHO the good outweighs the bad in the situation given to us...I always use heavier baits in the wind, to help maintain bottom contact..As far as using all flouro, I wouldnt do that, unless you only use subsurface tactics...Mono has its place, such as for topwaters and leaders for C-riggin...Also it gives a little more stretch which some people like for crankbaits and trap fishing....all depends on your preference and experience...

Try two things...first-as soon as you make your cast drop your rod tip to the water and let the line fall on the water this keeps the line from making that bow. This method is not great for sensing the bit on the fall but it allows the bait to hit bottom a lot quicker.

Second-Boat positioning might play a part in all this as well. Cross winds are always a issue. I like to fish into the wind but casting into the wind can be a issue as well so its a issue either way.

The reason I don't like fishing upwind...If your bottom fishing in a certain spot and stay up wind the trolling motor will make some comotion and that will stir up the water and send that sound and motion straight into the fishes senses. Not to mention if the water is some what shallow mud is kicked up and drifted right into the fish. Element of surprise is gone! This is true in freshwater and saltwater.

So, once again try different boat postions before you change line or style of fishing first.

I have even set anchor down wind before to stay on the spot with out using a trolling motor.
