Yes you can gain some speed useing some Custom strings.

We build ours with BCY 452X Cables, and a BCY 8125 string!! The 452 Gives you the stability in your cams due to it not stretching until late in your strings life (ruffly 10,000 shots) the 8125 is where the speed comes from but the downfall to 8125 is it will stretch! When we build the strings out of 8125 we let them stretch at about 350 lbs. for Ruffly a Hour to get the stretch out of them. But the same as the 452 once you get numerous shots on a Set it will start stretching but only slightly!!
