I can't speak for the cpxl, but I really enjoy my 2014 carbon knight. It's light, quiet and accurate if I'm doing my part. That coupled with decent speed makes for a nice bow in my opinion. I get many comments from others at the range on a regular basis and I couldn't be happier with my purchase; especially for the price I paid (RAK equipped CK's can be had new for $480ish if you watch sales).
