haven't used the magneium or the helium lineup, but own several kistler and a bunch of castaway rods, and all i can tell you is that if trey and billy kistler are involved it will be top notch stuff, when i lived in texas i fished with billy in a draw tournament, you'll not meet a nicer or more honest fellow, trey is following right in his footsteps, pricey yea, but they will stand by their products.
good luck if you get one be sure and let us know how you like it, also let trey know
