I have the Excalibur Mag 340 that I bought last year. From what I’ve read, the limbs of the Excaliburs that aren’t super high speed tend to last a lot longer than the high speed ones. So what have you guys heard/experienced with the Mag 340? I will always keep extra strings, but should I have an extra set of limbs on hand to? Is the Mag Max with the H.O. limbs far superior than the regular Mag 340 limbs?
