Won one, lost one and didn't even compete on NorthernLights at a certain point - I have a lot of similar loooooonnnng matching-multi-word domains I've picked up over the years, but I never sold one. Had a few low-3-figure offers, but no one seems to want to pay a premium price for a domain over 12 letters, especially those in the expansive 14-17 letter range.
I guess when your brand is 14 letters long, you've resigned yourself to a long domain and there is not much impetus to upgrade, say a 17-letter .COM domain to a 14-letter .CA domain, LOL.
