I have been fishing them for about ten years. Great, high end reels, and have never had a problem. The MGFV is great for pitching or flipping. You don't have to turn the crank to engage the spool, just push the thumb bar forward. Mine are all 7.1s. Shimano has replaced the Core 100 with the Mentanium, about the same weight as the Core 100, but with more line capacity. I don't think the Mentanium has the flipping mode. The Core 50 has been replaced by the Alderberan, another sweet reel.
