Deleting the Fingerspin Dimple Wasn't Enough - Brass Vs Aluminum

This perfectly leads into my next topic that relates to the dreaded center weight. The first round of prototypes used a brass threaded nut. I always liked brass because it is very soft so the bearing seat can be worked in over time, and doesn't gall as easily as raw aluminum. But I didn't realize the insane weight difference between such a small piece of brass vs aluminum. During the first rounds of prototyping I felt like the yoyo was decent, but I knew if I pushed the weight distribution even more it would bring the feel of it to the next level. I had removed the fingerspin dimple already but I looked into changing the commonly used brass insert to an aluminum one. I was shocked that it saved a whopping 3 grams total from the middle of the yoyo which I could then put on the rims. I never thought to do this because I figured such a small piece of metal was negligible. Boy was I wrong. This completely transformed how it felt. I remember showing Andre this aluminum seat prototype and when his face lit up with excitement I knew I made the right changes. Lastly, the bearing seats are anodized as well to reduce the chance of corrosion. Just because lol.
