I have been using the Thill 4 inch slip float in Australian salt water esturaries to catch Luderick (look a bit like a small mouth bass). I use the slip float in combination with a Rapala 7 foot graphite rod and Shimano 2000 series spin reel. The float is easy to cast and drifts nicely in the current. Its relatively light weight is a big advantage in not detering fish from biting. The high visibility paint allows the float to be seen clearly even under choppy water conditions. And the price, too cheap!!
