The Don gets its power and control from its dense stainless steel rims that weigh half of its total weight and the V shape feature blends into its shape for weight distribution. The size D bearing allows for outstanding rotational speed that enhances its performance and stability.
The Brasi Edition weighs around 1.2 grams more than the SS. The difference in weight is all in the rims making the Brasi Edition to feel a slightly heavier and more stable.
That is correct. The rims for this [Luca] Brasi Edition are made out of brass. The body keeps the same weight and dimensions as the stainless steel version (Vito, Michael and Vincent).
