All good advice from AlyCat.
I would like to point out one
key word in your post
"areas" I must not be using the right crankbait in the right areas or to its potential
You can have the best lure and technique in the world, but if you are fishing in an
"area" where bass are not present... guess what?
Like real estate, bass fishing is also "location, location, location".
If you are in the right location, sometimes it is as simple as vertical verses horizontal presentations. The bass may be looking for a vertical presentation like a jig or worm. If there was only one tip I could give people, it would be to "try to find out if the bass are reacting to a vertical or horizontal lure presentation". If you can figure that part out, it can dramatically reduce your lure selection and quickly increase your catch ratio.
There are so many variables when choosing a crankbait, it is difficult to say which one is the right one. I would suggest that you read this article by one of our prostaff members Frank L.
Article - Tools or Toys There is a lot of wisdom in this short article and it might help you fine tune your lure selection process.
I hope you find some of this information helpful.
