The SR35 series is MUCH better than Muteki's ring nuts, mainly because of the installation tools. The splined drive has a very flimsy installation tool that looks like it could snap if you just tighten it down. The SR35 installation tool and nose lock key are very thick and strong. With metal nuts, I know they will last a long time. As long as you use hand tools and NOT pneumatic tools, the product should be fine.
