Emerger, I am not saying no one is interested in you choice of gear, but you do seem to be going to great lengths to justify your choice. All I am saying is you don't have to do that – your choice is your business what anyone else thinks about it does not matter. I think you will also find that most anglers on this forum have, over the years, fished with every rod weight from 1 to 10 so they know the score. They have just made their choices as you have yours. It does not matter. Often these things are driven by fashion. In the 1960's glass #6 weights were the preferred "all round" rod in the circles in which I fished. The 80 and 90's saw the emergence of the barge pole and until recently you could not get a 10 foot 4 or 5 for love nor money (well, maybe not money!).
Fish with what you like best. Vive la difference!
