Adding silicone to their setup?? The reason this line is popular is its great to customise from the get go. Prior to customising i went out to hit with my bio100 in stock form and it felt hollow and unstable. Normally i put 50g around the handle and 20+ at the top hoop. Does anyone puts silicone in their 100's or is it just me? does anyone use foam silicone and not that home depot clear stuff which us difficult to measure. i normally use cured silicone for making moulds allowing me for more better application, and more importantly the better grade silicone imo feel softer and more shock absorbing.
