Fishkisser-
You are not going wrong by getting a Teton Reel. I have the lower end Tioga in an 8 weight version and it is sweet. They sound GREAT, nothing like a Pflueger. The Tioga which runs for 120 has the same exact Drag system as the uper end Teton, the only difference is that the Teton is lighter and more machined out. My Tioga Is just the regular 8 weight, it can hold my 8 weight floating line and around 180 to 200 yards of 30 pound dacron backing, it can hold 220 yards of 20 pound. The large Arbour might hold less Im not sure. But I can tell you, that you wont have any complaints with either.

Fun Flyfishing- Josh
