There are quite a few good string makers...One of the best is Carters Archery (
http://www.cartersarchery.net/ ). He goes by Crackers...If you like a perfect tune along with strings and cables, he'll tune your bow to absolute perfection. I've sent four bows to him and every one shoots to perfection and stays that way. I mark my cams to reveal any movement and after 7 years, the first one he tuned hasn't moved at all. The strings and cables haven't stretched at all! He'll make them in any color combo you like (you can match your arrow fletching and wrist sling if you like that...)
Another well established company is Winners Choice. They make great strings and cables also...
I wouldn't be afraid of Vapor Trail either...They make a good product...
In any event, either send it to someone (I would recommend Crackers highly) or find the specs. on your bow and get the bow into spec. Make sure cams roll over properly (that they're timed properly), and the brace height/draw length/axle to axle are correct. This stuff is all crucial to accuracy...
Hope this helps...
