I dont think there is any hype about pins. There may be over enthusiastic comment from one or two, and of course there will always be folks who try to tell you that if you cant use a pin, you are not a proper angler. Well, fair enough, each to his own opinion. Like a previous poster, I cant Wallis cast, and probably will never learn, but I do use a Speedia everytime I fish for barbel. On the second rod I use a shimano baitrunner. This is for purely practical reasons.
After it has gone dark, I would go boz-eyed trying to watch the isotopes on two rods, so I fish one rod on the pin, and watch the isotope on the other. When I get a bite on the pin, the ratchet screams out.
Now of course, all these things are purely personal, but I find that one of the most exciting aspects of my barbel fishing; when that pin screams out in the dark. I personally find playing a big barbel on a pin (pin pb 12:0) to be much more exciting than on a baitrunner (baitrunner pb 12:13).
So I dont think its a question of hype, I think its a question of personal preference. I find using a pin very, very exciting. Others may not. Fair enough
