the banshee shock is only like 14"s so their is not enough lenght to go with a triple rate and see any benefit. A triple would be better if the shock was longer. Like on the hondas which are 16.5"s you have enough room to fit a set of variable springs to benefit.
I like the elkas better because of the ride height adjustability is much easier, and they have a higher resale value if you for some reason down the road decide to sell the quad.
Plus when you go to rebuild them you can always add the reservors and get super plush suspension. the elka has 5/8" chromoly shafts also which are very beefy.
