Why not a sink-tip line ?

Hey guys been trolling here for a while and finally joined to try to get some straight up answers from the veterans. I'm not new to fly fishing but am new to fly fishing the Salmon River, i.e. I haven't yet, but will come the 2014 season. The fish have been kickin' my but on spinning gear for years so so I haven't even had the nerve to try on a fly rod. Well gonna bust my cherry next year,sooo... now come the stupid questions from the rookie. From what I read and have observed on the river why doesn't anyone seem to use sink or sink tip lines to get the fly down into the "strike" zone?

I have occasionally used a sink tip looped on the end of a floater to swing flies. Had varying success. They tend to hang up on the SR, unless you're in fast water, and if I'm swinging flies, I'd rather get bit by aggressive fish up in the column than skulkers on the bottom. They are useless for drifting nymphs and eggs, as you lose all control and feel. They would be good tools for lining and snagging, but that's beyond  dead last on my list of usefulness. I have used short pieces of lead core tied into the leader between the butt and the mid section to get flies headed down in the winter. That worked OK.  I use lots of sinking  shooting heads in other fisheries, but the SR doesn't seem to be conducive to their use. Just my opinion and experience, anyway. Good question!

Like fichy said, it gets hung up easily... there are areas that would swing one well with good water flow but on average a poor choice and your tip will end up getting beat up by the rocks

   War Eagle welcome. I have learned alot from people on this board it has definetly cut down on the learning curve and gets you through the days when your wishing you were fishing.
