None taken. The high performance string material will generally last a long time even with no wax. I'm one of the world's worst about keeping a string waxed myself, and I can remember only one time in the past 10 years or so where I've actually worn a string out (had nothing to do with the lack of wax). I usually just get tired of the colors, or it gets fuzzy, or nasty, so I make myself a new one. However, keeping them waxed will generally make them last longer, especially if there's a point where there is friction. The weaker the material, the more benefit it will get from wax. Bow poundage, the number of strands, how often it's shot, how it's made, etc. will also have an effect.
Wax does not hold B-50 (or any other material) together--it won't get fuzzy as fast, but if you are willing to deal with the aggravation of making a string without the aid of wax, it will work just fine. Although it's sticky, wax is a lubricant, not an adhesive--at least when it comes to bow strings.
