Re: 6wt Saltwater Reel for Sage Xi3
-1 for the Teton/Tioga. I own a Tioga 10. There is a lot of backplay prior to engaging the drag. Plus, the reintroduction by the new owner has been sort of iffy. I don't know how certain their future is.
Anodized aluminum and either a sealed or easily cleaned drag. Most good reel makers will make something appropriate. For a 6wt., I doubt you need the strongest drag, but you'll need smooth for the speed of the fish in saltwater.
