I am not cranking expert, soft plastics are my forte, but i will tell you what works for me in a a few short sentences (the basics)
Diving depth - there are many different depth ranges available, from 1" - 20+ feet. Determine what water depth you will be fishing, and get a few different models covering that from top to bottom. Don't rule out the 1"-1 foot baits, (manns minus 1, bandit footloose, etc). Sometimes those provide hellacious action, and it is like fishing a topwater. You'll be able to notice a the difference in the bill of each lure, this is what determines diving depth. The length and the angle of the bill determine that.
My general rule of thumb is to fish a bait that runs deep enough to hit the bottom, or to tick the weeds if fishing over weed cover. Now something can be said about suspended fish, but no need to over complicate right now. So, try to make contact with the bottom or tick the tops of the weeds. A pretty simple cast and reel retrive will be good to get you started. Then you can incorporate variances into the retrieve, stop and go being my favorite. Especially if you hit bottom, pause and let the bait rise a few inches, and start again, repeat. If you tick the weeds, you may need to rip the rod to clear them, and many times that draws the strike.
Colors, i usually choose natural patterns in clear water, dark patterns or bright patterns in dirty water, as a general rule. Expanding upon that based on sunlight, etc...
The above is basic, but it will get you going. I vary my presentations taking this much further by choosing a wide wobble of a tight wobble based on water temp, and I like to weight many times to suspend rather than rise on pauses, etc...
Bait casting rod and reel by far a better choice, if you don't already have one. I still have my first combo from when I was 14 (quite a few moons ago).
Good luck, and I'm sure somebody will give you more detailed info than I can, but when you are ready to talk about Texas vs carolina riggin, look me up! :wink:
