I use both topraiders and turbo jacks...They have a different sound from each other that is very noticeable atleast to myselff and probably to the fish. I personally have had 10x more success using topraiders but i also use them alot more because i have alot of confidence in them. The turbo jack rides higher in the water and doesnt push as much water as the topraider either. They both have their time and place...my 2 cents..
