Just to add more confusion to all the theories.....I have been building custom rods for years and have always quietly smiled when using exposed blank reel seats. As though there is something magic about being able to touch the surface of the rod blank. I can tell you that when a reel seat is properly fitted and glued, where vibration transmission is concerned, it becomes a part of the blank. There is no vibration imparted to the blank that can escape the reel seat when it's installed properly. The difference in touching the blank surface and a properly attached reel seat are at best imperceptable. Any vibration felt in any rod blank when fishing must be transmitted, in this order, through lure, line, guides and the reel. The rod blank is the last to know, which causes me to lean toward Ghoti's theory that a reel might be the best place to "feel" a bite or the bottom. When fishing with tight line techniques, I feel the bite with my whole hand. With slack or semi slack techniques, of course, I'm a line watcher. IMHO, the best case for spending more money on light, well balanced rods is day long fishing comfort and specific lures/techniques. "Feeling the bite" is way down on my list of reasons for great rods and I have a bunch of high end rods. Fishing for 10 or 12 hours without feeling like I rowed a boat all day is much more important to me. But then again, I'm not a real "sensitive" guy. LOL
