Dang. Sorry to hear this. It would be helpful to know more to be able to give some guidance.
Generally though braid is no issue especially on a stained lake like Rayburn. I would suggest a leader though to make it easier to switch out jig sizes and colors using a swivel and snap. Use 10 or 12 lb leader of any sort. The snap will also help you find your jig on livescope which I'm guessing you have based on your budget! Rig up 4 or 5 different double jig combos with a combo of smaller and larger jigs, hair jigs, plastics, colors, and even a gold hook for a minnow.
Move quickly if you don't find aggressive fish. If you don't get bit within a few minutes it is on to the next spot. Catch a few and still see fish down there that won't bite, move to the next spot! Livescope will hypnotize and slow you down if you let it.
I would call Greg Fenn and go on a guided trip. Not sure if he would do a electronics trip on a customer boat but that may be an option.
Lastly, welcome to this frustrating love affair with crappie!
