I'm pretty sure these are very new tires. I think Dunlop just introduced these within the last month or two, so it's not likely you'll find many people running them yet. There aren't even any reviews on Tirerack for them yet.
Here's some particularly nauseating marketing crap from Dunlop. Maybe there's something useful buried in there. Hey, it's got 5-Pitch technology, Jointless Band technology, Max Flange Shield and Silicarbon Matrix. That certainly sounds impressive.

What the ****? It's a tire!
Anyway, sorry for the mini-rant. I think the short answer is that you may well be the first person on NICO who has this tire if you get it. Maybe Grant has some input on it. I think Tirerack does a fair amount of testing on new products.
