Deep, I'm a hard core revo user. I bought 8 stx reels when they first came out. I bought an Sx and swapped the gears from a winch to get my own SX in a 5:1.1 ratio. Before I bought all the STX reels, I had a full set of Curado SF reels and a couple of Chronarchs. I was instantly able to get longer casts with less effort, but my over run occurrences went way up. At first I thought I had lost my touch. I did some research and found that you set them up a little different and I tried that. It helped a lot, but I still got more over runs than I used to. I almost decided to sell them all, but I stuck with it. I learned that I had to use a little more tension and a little more thumb, but I always knew that although they were smooth as silk, they were more prone to over run. The Sx on the other hand worked a lot better for me. It doesn't have the 2 part spool shaft and after it was cleaned and tuned, it casts great with hardly any over run problems. Last year I had almost decided to sell all the STX reels and replace them with SX reels. I heard that the 2010 STX reels would have dual brakes so I waited to check them out. The first time I tried one I knew I had found my reel. The dual brakes cover the start and the end of the cast and I can cast virtually thumb free now. I sold all the pre 2010 STX reels on ebay for around $130 each. I found an ebay dealer that had the new 2010 as a buy it now for $164 I bought a couple and then saw that he was also running some on auction. I replaced the rest from the auction and got some of them for $130 to $140. I had a good reason to stay with the revos. I liked the size, the shape, the quality and the drag power comes in handy when I fish for wipers and stripers. If you keep the pre 2010 STX, you will always have to use more thumb than you use with your other reels, that's just the way it is, but you can learn to use it with a minimum of over runs.
