I don't have extensive personal experience with them but I've seen multiple that were just plain bad (more TCI than Hughes). Friends of mine at the strip as well as the doughnut had issues with chatter, improper stall speed, and the stator. I know one guy that lost a season because of TCI. Everyone makes mistakes, and it's been quite a while since this happened but it seems there are "better" options available nowadays. They certainly ran at the head of the pack for a while, and still do for some, but I have a hard time trusting any of the old mainstays because the generation that took over can't be trusted to know their product anymore. Yank, Circle D, and Pro Torque appear to be superior in my eye but it's good to hear a positive review. Enough of them will get me to change my mind.
