I haven't used the thing a lot so far for bass but even croppie fishing it seems to me the bobber just about has to be stationary......the longer the leader the bigger a pain in the but it is to cast though....I tried the slip cork but had to add additional weight to the line to get it to pull through the cork.........I have found the little pear shaped plastic bobbers that the line slips through and have the little twist lock thingy on them makes changing depths a lot faster and eliminates the need for the 3 way fastener and and the leader.
