>Say you just arrived at a lake. Do you rule any lures out by the water temp, clarity, or weather conditions?
I don't rule out anything entirely, but topwaters take low priority in cold water or bright, sunny conditions.
>How can you tell what the bass want on a specific day?
You can't predict in advance, even though there might be some general guidelines. It's a trial and error thing.
>Also, people say, "The bass will tell you what they want" How long does it take for you to find out?
Sometimes, the whole day passes and you don't find out.
>What are the first things you do differently to ge a bite? Do you change color, retrieve, or even lure?
I might change the retrieve, but after that I'll generally change lures rather than just change color.
>I hear all these talks about well you gotta find that pattern and stick with it. Wouldn't it take forever to find the pattern?
It can.
>With so many different lures in ones tacklebox how do you know which ones will produce on a given day?
See above. You don't, you experiment to find out. Obviously, you need to fish a lure that is compatible with the cover and depth you're fishing. Then there are personal preferences and confidence lures. Under the same conditions, five different anglers might choose five different presentations. Just read as much as you can and put in your time to determine what works for YOU.
