Hi Gunston,
I don't use the carolina when trolling or even in a kayak or boat (except if i want to keep a livey near the bottom), But when i'm beach fishing, Mainly to get the extra weight of a sinker on thier that a jig head can not provide, so my cast will reach the back of the breakers.
You can get bigger sp's that have the weight but they are a bit big for the standard surf fish. Unless i was somewhere that had deep gullies or a steep drop off where i would pick up jew's
But for this its great.
Cheers Dave
