I shoot goldtips and I like em...I think they are a little heavier than what you are looking for but check their website...they also have calculators. I can' t believe how strong they are...they only thing I' ve seen that tears them up is putting another goldtip right in the nock of the first...I' ve had a coulpe misses, and missed my target....went through the sheathing(of my garage ) and smack into the brick...sure tears up the field points but the arrows are good as new.
