with water in the low temps for the winter it is a tough gamble the big question is to go fast or slow each have big advantages or disadvantages.
hardbaits are a great tool in the winter but the problem is you are trying to get the fish to react to it, it is like setting off a trigger in theyre head to eat so they do sometimes you have to cover lots of water and hit them just right to get this effect baits to try would be, rattle traps in stained water, crankbaits diving to appropriate depths and for various conditions. it really helps to be able to locate fish before fishing reaction baits unless it is decent enough fishing to use it as a search bait witch can be a hot ticket for cold water bassin.
in my opinion the easier of the two would be soft baits the best baits for winter seem to be baits such as dropshots and darterheads with 4"-6" finesse worms going slow with pretty light weights, other baits that can catch fish could be senkos, shakyheads, and other finesse baits similar to those but my personal preferance is to use a big jig in the winter like a 3/8 oz - 1/2 oz big bodied jig with a big trailer like a reaction innovations beaver it really takes a lot of focus to fish these baits becuase you greatly diminish your bite ratio but you get bigger fish, you have to think of it as hibernation the fish still have to eat but they will be trying to find the best meal that is available that takes little energy, witch unfortunately for some means stocker trout
the trout are like sticks of butter! the bass wait behind cover and dart out inhaling these unsuspecting high in fat and protein meals, if this is the case use a swimbait such as a huddleston deluxe, fish it slow and even let it sit on the bottom for a few second then swim it a few feet...talk about a hard to fish bait, big swimbaits are really a test of an anglers mental ability to perservere for hours without so much as a tick but when you get bit by a big one its about as much of a rush the human body can stand (especially in a pontoon boat), anyways hope this helps give you a little more insight about winter bassin it takes lots of skill dedication and time to even get bit but for those willing it can pay off big.
ray: keep an open mind and wait it out if your one of the daring and willing.
