Assembly Instructions Product Description These Zippy spacers designed for the BBbarfly SuperFly balisong trainer are made in-house from a rubbery, shatter-proof polyurethane. They add positive jimping to the SuperFly for extra grip, and include a tungsten weight system for adjustable balance. Features Deepens sound. Positive jimping for extra grip on ladders and chokers. Adjustable balance: Each spacer houses 3x removable Tungsten weights to fine-tune the balance to your preference. This weight system offers more granularity compared to the stock system. SuperFly Handle Inlays sold separately. Each Zippy spacer weighs 0.04 oz, and up to 0.102 oz with all 3x removable tungsten weights installed. For comparison, each stock brass weight weighs 0.047 oz (0.093 oz for a set of 2). A BBbarfly Superfly Zippified with both inlays and [unweighted] spacers weighs 4.33 oz, or 4.26 oz with just spacers. For comparison, a stock BBbarfly weighs 4.367 oz stock (with all 4x brass weights). Recommended Balance Configurations My personal preferred SuperFly balance is with inlays + spacers (no tungsten weights installed). This configuration weighs 4.33 oz total.
