Lastchance,
I have a Hardy "Perfection" glass rod - old school. I can tell you that premium glass rods fish great. They tend to be slower......in fact, much like bamboo, but without the weight. The rod "play" upon a hook-up transfers much more "feel" than most higher tensile rods.
For fishing big water, I much prefer today's high quality graphite/boron type rods with a lot more strength and a faster action.
But, for smaller waters, a QUALITY glass rod can be very refreshing. In my opinion, of course.
A good, high quality glass rod is not the old, mass produced fiberglass rods that many of us old timers grew up using and were very happy when graphite came out. No question about that. But, high quality, great taper designed glass rods are light years ahead of the old Fenwick glass rods of the past.
