Winners Choice or Vapor Trail would be among my favorite bow strings. In fact, I am picking up my brand new Mathews Reezen tomorrow and I am changing out the Zebra that comes on it for a Vapor Trail. These two strings have less stretch over time, absolutely no twisting, and seem to be a little hardier for the guys that work on them a lot or abuse them as I do. The Winners Choice are great also but be prepared to spend about $140 or so for a string and cable. I believe you can get the vapor trail string/cable for around $70. I used to like Zebra stings until they switched to the new style Zebra string that they come with now, I seem to have twisting problems with my peep and deserving around the cams. I am sure not the norm but enough for me to justify the switch. I have been through 1/2 dozen Mathews bows with Zebras.
