I acquired two vintage Fenwick HMG fly rods for the wife and me, and need help deciding the best weight of floating, weight forward line to use. Both rods are 2-piece 6 weights. One is GFF 806, the other GFF 856. I determined the actual weight of the rods per the Dr Hannemans Common Cents system [log in for link]
as I first observed on a Youtube post [log in for link]
. Both rods measured 5.35 on the scale. Internet posts show the action of vintage two piece HMG rods as medium fast.
I am an advanced novice, and my wife is a novice. We fish from shore, and prefer streams and small rivers, such as the upper Rio Grande--which I view as our sweet spot--in the area of Road Canyon Reservoir above Creede). As we improve I expect to branch out to larger waters, possibly including Spinney and the Arkansas River et al. I am inclined to go with 6 wt. line, expecting that it will help load the rod well. However, I don't know how the medium fast designation fits into the mix. We are seniors, and so need the easiest casting scenario possible. Any help is greatly appreciated.
