Ingot Greaves or Golden Hakama

i’m HR40 with only base game running the Night Eternal Hammer and my current skills are at Crit Eye 7, ATK Boost 6, Crit Boost 1, having no access to crit jewels, is it worth it to go down to crit eye 5 atk boost 4 for Crit Boost 3? with current setup i’m at 85% affinity, 100% with WEX 1, also how valuable is WEX for hammers if you mostly hit the head outside of spinning bludgeon? it doesn’t seem like there’s many monsters that have a head weakpoint so i’m confused on it being recommended so much unless it’s just assumed to always know weakpoint location
