We use only the best materials at ProString to give you the highest quality product. We stock BCY 452x and Brownell Astro Flight for the 2 best choices in the business! Check the Faqs page for more info on the material. If you are unsure which you want we can also help you decide what will suit you best if you contact us at Sales@prostring.com Our premium strings and cables get served with Halo on all cam contact areas at no additional charge!

Our premium strings are pre-stretched during and after the building process to ensure stability, minimal to no "shoot in", and no peep rotation.
