You can run anything that you want behind leadcore, so go ahead and experiment. You can also run core off of boards, so if you think you have spooky fish, you can give that a shot (you COULD clip the leadcore right into the board release, but you risk damaging your core/line, so I don’t recommend it)
The leadcore will get it to the bottom, but you will need to know how many colors to let out… It probably won’t quite bang bottom like a billed crankbait, so you might need to pay a little more attention to depth/depth changes vs colors out vs speed. I would let the leadcore be your weight, vs trying to add aditional weight.
The other thing is speed… Spinner rigs are generally run much more slowly than summertime cranks, so you will need less ‘core out. You probably won’t be able to run a mix of cranks and rigs very well for this reason. Generally you are better served with bottom bouncers, beadchain sinkers, 3 ways, etc, with spinners but go and try…. Worth a shot!
