Sig,

Hmm.. Perhaps they put in some extra twists to get that "heavy 60"? It doesn't take many twists on the duallys to ramp up the draw weight. I do know that BowTech really doesn't make "heavy" bows like some other companies offer upon request, though I've seen dealers swap rockers and/or twist up cables to do that. On some of the bows (depending on limb deflection and rocker size) you can switch rockers to get a bit more. On some bows they already use a tall rocker and what you get is what you get.

Shoot me an email and I'll see what I can do to help.
