I am pretty sure it isn't the because of water since it frooze up while walking to the river. Didn't even cast it once. I took it apart and the grease that was in it was all clumped up and fairly thick.campfire said:Well, I am not what you would consider an expert but I will share my thoughts. First don't discount the ice. In cold weather it is very important to be careful not to imerse your reel. Mine never freezes up from the water/ice comming in on the line but if it gets dunked in the water it will freeze up very quickly. As for the grease, most fly reels have fewer moving parts compared to spinning, trolling and bait casting reels. The problem may not be with the type of gease but the amount. I don't think fly reels need as much grease to lubricate them. I use a very light coating of regular patrolium jelly on just the moving part surfaces. Vasaline is lighter than most reel greases and might not conjell in lower temps and don't use too much. My 2 cents for what it is worth.
