I would appreciate some advice about fishing buoyant lures with weight.

I know how to fish Kwikfish with a weight on a drop line.

What I would like to know is if Hot Shots or Tadpollys can be fished effectively with this technique.

I have heard that some people add split shot to fish deeper.

Can someone please provide some advice on the above, or other tips to get my lures down to the fish?

Thank you.
