The DNS or the "Do Not Stack" is the next offering from Kyo and Kyle Weems has created another great precision metal yo-yo. The yo-yo is thick and incredibly durable and it's lighter than it looks at 65g. It's got incredible balance and uses a sheildless size C bearing and dual Vapor O-Rings that sit nearly flush for the response system, which can be replaced with flowable silicone or any other YoYoJam size O-ring. A great yo-yo for grinds and it comes very unresponsive with a huge gap at 4.36mm. Supplies are very limited and as with any Kyo yo-yo these will go fast. These are considered B-Grade only because of one or a few small flaws in the finish of the yo-yo. The yo-yo still plays like an A-Grade but Kyo puts a high priority on quality, and even though the flaws a minimal he has decided to knock $50 off the price so you can afford an incredible throw.
