FC don't sink like friggin rock !
Nylon don't float like a friggin cork !
FC sinks and so does Nylon after a while, none is naturally buoyant.
FC STRETCHES ! depending on the brand even more than certain Nylon brands.
Nylon AIN'T no friggin rubberband !
So, what do I like ? I like nylon, yup, plain old *mono* as you fellas wrongly call it since FC is also monofilament line, why ? because ... I HATE FISHING WITH A FRIGGIN SLINKY ! which FC is no matter how much line conditioner you apply to the stuff. What do I like about FC ? man you can almost know what the fish are thinking before hitting the bait, but I like the more *tame* behavior of nylon.
