I am a loyal, very happy St. Croix rod owner. All of my rods that I fish with are St. Croix. I have 2 Triumphs, 2 Mojo, 1 Avid, 1 Premier, and a Rage. I haven't caved into a Legend of any sort simply for the money. I have yet to break any of my rods, and they're all in outstanding shape. Honestly, no matter what class of St. Croix you go with, they are worth every penny.
Since Avid is being discussed the most, I have the 6'8" Medium XF avid spinning rod for finesse fishing. The rod is amazingly sensitive. If you're grip choice is not a factor and you're good with cork, go with the Avid.
