I'll be fishing tomorrow, but can't decide to fish Nolin or Rough.

Here is the problem:

1) I know where to fish at Rough, but since the water is low, I don't know what ramp to put in at to get there.

2) I know where to put in at Nolin, but I have NEVER caught a crappie out of that lake because I have never fished for them.

Suggestions?
