@Fam-man with all due respect to @DanE who actually got me on the right path to getting stargazer right, I haven't upgraded to z-box cause stargazer seems to pull very nice on both my boat and my ski partners boat 35 off skiers and although, I only get on Zero off a few times a year, the only difference I can feel is a faster gate with stargazer. My partner skis an occasional tournament and skis the same ball count and doesn't notice much difference. We are both on the lighter side (160 lbs) and that might count for something. I suspect z-box reacts much quicker and might be the difference for a heavier skier or puller.
