I just purchased a Martin Panther a couple of weeks ago. It's my first recurve bow. I've always shot compounds over the years, so I'm not that versed in them. The question I have is can limbs from other manufacturers fit on the riser, or do they have to be Martin Limbs? I'm just wondering honestly. I don't have any intention to get new limbs yet, but reading on the web the limbs seem to be the weakest link it the bow.
