Before anyone gives a groan, I have searched the threads and found very little (usually mixed in with other subjects) on this comparison. I have heard that Helicore Pizz are Daddario's version of the Spirocores, but all I can really find is a comparison with is the Hybrids. Are the Helicore Pizz comprable, or should I spend the extra and get the original Spirocores? How are they similar, how are they different, durability, etc. I need some objectivity here, not just stubourn opinions of what I should do. Thanks.
