I plan on going fishing to my nearest lake. I plan on only fishing my keitechs 3.8. The reason is I need to get comfortable with them by staying them. Don't care if I get skunked. What I need to know is should I use them on a underspin or just the weighted swimbait hook with screw lock? The water I fish has been choc milk and windy. Very cold. Water has been at 33 degrees the past few days. 

If the water is chocolate milk, I’d go with the underspin for sure. 

X2 underspin will put off some flash and vibration in your chocolate milk lake. Clearish water I'd opt for just the jighead

 

But, 33° water I'd try something a little more slower in presentation. Not saying you won't get bit, but don't limit yourself in tough conditions. If it was 60° water, yeah throw that keitech till your hearts content. But at least put a black and blue jig in your pocket when you go!

Use a Colorado blade, if at all possible. You want as much vibration as you can get while reeling as SLOW as you can in the water you described. 

In those conditions I think you'll have your best luck on the couch in front if the fire.

No bass in 33 degree water.

I've caught Bass in 38 degree water, had to break ice to get out of dock, but that was clearer water. At 33 and muddy, I'd stay home or find better conditions, lol. But if you are determined, I'd slow roll it with the underspin.

The Gambler Duz-It has worked for me in all conditions regardless of cover or clarity.

A small swim jig may work good.  It gives it some bulk and you can put it right into the cover they will most likely be up next to.  I like to use 1/8ths on a 3.8 or 4" easy shiner.

Don't form an opinion on the effectiveness of a swimbait, underspin or not, under those conditions!

I'd go with a swimbait hook with the belly spinner, like an Owner Flashy Swimmer. That way you'll still have some flash and extra thump, and you'll also be able to reel as slowly as possibly and reduce the risk of snagging. You're odds of catching a fish are extremely slim in those conditions, but you won't catch them at home. 

At 39.4 degrees water starts to hold high concentration of DO decreasing it's specific gravity (it gets lighter weight ) raising towards to surface and freezing at 32 degrees. Bass aviod water colder then 40 degrees if possible do to too high levels of DO ( dissolved oxygen).

Use you sonar unit to locate bass, then use a underspin with swimmer if you are determine to use something bass are not looking for.

That cold water, good luck. ?
