I currently have a fox DHX on my sunday. I'm thinking about picking up an avy-converted 5th or swinger. I know the springs are not swappable, but what will fit on either the 5th or swinger? It's very hard to find Manitou labeled springs, but I was under the impression that it's like "Manitou/RS/Cane Creek" then "Fox/Avy/Elka/Zokes".... is that right?
