I have used the Vapors for 3 years now. They are by far the best arrow I have ever used. They are all carbon construction for great performance. They have a four color logo on a 32.5 inch charcoal black finish. The Pro's have a +/-.0018 straightness tolerance at 32.5 inches. +/- 2.5 grain weight tolerance per dozen. The 3000's are 7.9 GPI, 4000's 8.9 GPI, and 5000's 9.2 GPI. Here is the best place I have found for price. Archery Experts
