Yep - I switched to carbons about 2-3 weeks ago and am experiencing the same thing. I' m interested to see what everyone else has used but the two things I have tried was non-stick cooking spray - I spray a rag/towel and wipe about 6-7 inches of the arrow. The other thing I tried was liquid dish detergent - same thing - wipe last several inches of arrow. Both made a huge difference.
