I have a couple of the first gen Revo STX and a couple of the early Silver Max produced at around the same time, and have not had any problems with them. I don't fish often enough for them to be a better reel than they are, so they do what I need.
I have several of the older ABU round reels, some even made back in the 70's, and frankly prefer them but also do like having the low profile reels too.
I have added a couple of Black Max & Max X to try some left hand reels, and keep the price reasonable. So far, I've not used them enough to have much of an opinion, but they cast fine and I expect they'll last me as long as the other LP reels.
I feel that ABU ( Pure Fishing) is playing too many games with the names now, and it's hard to tell which is a "better" reel, as the price tags & reviews I've read don't seem to fit.
