This bow is phenomenal. Its accuracy is unapparelled. I put 200 shots through the Viper today. I don't know what you did to the strings and cables but they never show any wear. I haven't put anything on the strings or even used any rail lube. This is the perfect crossbow.

Well-balanced, compact size, and unprecedented features all add up to the ultimate package in crossbow performance.
