I like a faster setup. But use a middle of the road weight arrow. Frank' s example shows, to me, the heavier arrow is not detrimental within 30 yds. As far as trajectory goes. Beyond 30, the lighter arrow' s trajectory becomes a plus. Aiding in shot placement as it relates to distance estimation. At that point, what' s better? A well placed shot with a lighter arrow? Or a poorly placed shot with a heavy arrow?
