I can only imagine what you guys are doing to freeze up a Tioga.
Redingtons were infamous for it, but that's the first time I've heard of it happening to a Tioga. I know Teton suggests a light oil but I like a lightweight grease as it doesn't wash away and generally lasts longer. That may help. I've also seen the light oil leach into the reel and contaminate the drag washers too. I've also noticed they are shipping reels without any oil or grease on the center shaft lately which makes for a squeaky reel. Makes no sense to me...
I also wonder if they changed the metals a bit on Tiogas, mine are all fairly old (maybe a decade even) and I've never had an issue at all.
I've got a few Tiogas, a Bauer, and then everything else is Tibor. FishHawk you'll love the Tibor; picture a Van Staal only even more bulletproof...
