Everything I have read, seen on casting videos and heard from the experts told me never to use a snap - T when casting heavily weighted flies. I even warned a fishing buddy who insisted on doing so and still does even after taking the tip of his new switch rod. I was fishing river left with a bridge very close upstream for Chum. My fly was a cone head articulated rabbit strip monstrosity coupled with 10' of t-14. After hitting the bridge a couple of times and loosing one fly using the circle-C , I resulted to yes you guessed it .My 15' , 9wt. T & T is now a four piece. Let this be a lesson to anybody starting out or is as stupid as I. Don't be tempted.
