I recently decided to take my freshwater fishing a little more seriously, so I decided to invest in a baitcaster. I bought the promax combo at 100 dollars, which was a great deal. The reel casts like a dream, and reels in smooth as ice. However with my first reel, I began to notice a few problems. The crank would sometimes stick, and the gears would start to get a little squeaky. I decided I may have got a lemon so I want to the store and exchanged it for a new one. Went out and I was casting like a dream again. A week later the same thing started happening again. So I went out, bought some abu garcia grease and decided to grease up the gears. I thought maybe I was flushing the grease because after each trip I give my rods a good cleaning. This worked for maybe a half hour, and now it's back to grinding. Is there something I'm doing wrong? Is this a common problem with this particular reel?
