The Stick's sight window isn't cut as close to center as the Dreamcatcher's. That means the arrow is pointing further left with the Stick, so it needs a significantly lighter spined arrow to come around the bow and shoot where you're looking. You might be able to change spine enough for those arrows to work with the Stick by switching to 125 gn heads. I don't know.
Sometimes I wish I had points made from depleted uranium so they'd be heavy enough to loosen up an arrow's spine.[:-]
