Well just say...
If you want speed here's the recipe
Long draw length, high poundage, 5gpp or lower if you're daring, less weight on the string, few stranded string, 8125 instead of 452 string , the occasional brass nock near the cams will buy a few feet, feathers instead of vanes,no wraps, roll the cams aroundby twisting the cables (if applicable),and you can always buy a faster bow.
