I've got a Pro-tec with xt2000 limbs at 60-70# and found a set of Ultra-tec xt3000 limbs, 50-60#... just begging to be put on for indoor this winter, would this swap work? I'm assuming a cable and strinc change will have to happen as well. If they will work on the bow, would it be worth it in your opinion? Draw length is 30" if that matters.... thanks folks for any guidance.
