My only dislike for weights and tadpoles is when fishing near the bottom, it easy on a turn to slow down and run it in into to bottom, nor there is grass, shells, worm gone.

I have and tried tadpole behind my small boards and had this happen often, when I run jets I don't get this. I also don't shuffle my boards, so if a middle board comes in it goes back to middle by letting straight out the back then letting it pull up into slot. And doing this will almost 100% put my bait on the bottom b4 the board pulls up.
