Thank you Mike. That was a similiar response that I got from a couple of different places. I contacted Sage company, and per one of their reps, They indicated that the Beulah elixir SWITCH ROD line should fit on the 1680 reek with about 100 yards of dacron. They suggested that if I go this route, that spectra braid would offer more backing, but make sure to lay a base of Dacron backing first to prevent slippage. They estimate that I might be able to get 175 - 200 yards of spectra backing with that particular reel. They did however offer suggest going to a larger size reel as you did.
