For anyone looking for a quick fix to huntmaster limbs, I've been told that Samick Sage limbs will work on Huntmaster risers, but that they do run heavier than marked.
I plan to get some 30 lbs limbs (which he said should pull at 32-34 lbs) so I can have a loaner bow for my non-archery friends. The person who relayed this info works for a non-sponsor, so I'm not sure if I can name them on the forum. Rest assured, it's a reliable source, however :)
