I am currently shooting a Halon 32 6 with 31.5” draw length and between 55-60 poundage. According to Black Eagle’s chart, I am between a 300 and 350 spine. What would be the pros and cons between the two? Also wondering if i need to be shooting a 31.5” arrow or should leave it at 32”. Looking at carnivore and zombie slayers. Thanks for the help!
