I personnally have been shooting exclusively Stone Mountain Dakota Prestreched Bowstrings for many years and have nothing but good experiences with them so heck ya I asked them for sponsorship.
I have been a Archery Pro Shop Manager and Technician for the last 3 years and have hadthe opportunity to tryalot of different strings and had many companies offer me free strings and I have turned them down cause I am more than happly with Stone Mountain's Strings.
I find the Stock Fuse Strings on the Hoytsto be seriously lacking,definitly go for the upgrade in strings unless you want to constantly re sync your cams from the string and cable strech.
Acctually the String of choice by most of the Archers in my area being Bowhunters and ASA and IBO 3D Competitorsis Stone Mountain Dakota Prestreched Bowstrings.
I feel the Winners Choice are good as well as Gibblets, Vapor Trail and the G5 Metrao Strings.
