Of the ones you mention I would choose Bucknasty. I have used Winner's Choice and Bucknasty strings are actually a little better in quality, but at less cost. Next choice would be Vapor Trail and then Winner Choice.

I would not touch Zebra strings even with your bow and checkbook. They are a waste of good hard earned money. In fact they very well might be a step down in quality compared to what you're using now. The Mission and Zebra are made by the same company. Your bow deserves better.
