My two cents on this.....
I use line for what I feel is it's best intended purpose. My general rule of thumb is as follows....
FC> Jigs, most soft plastic (especially weightless senkos and such)
Mono> Crankbaits
Hybrid Lines> multipurpose here. I like it for spinning gear. Most 6lb test works for me.
Braid> Punching heavy stuff and thick coverage. Overall, I am not a fan of braid as general all purpose line. I will save my breath as to why and move on.
On FC though, depending on the line, I like how it handles for most bait casters. I have never had any real issues with it. My big thing with FC is that it last longer,IMHO, than mono and I can depend on it to be, for most part, consistent in it's properties. My only gripe is the cost. Like most fishing things with added benefits, the amount of return does not equal the price.
