You can be that guy. But i don’t want to be that guy also. We were talking about engines, and there is only one with funky blades, so i guess there’s your answer. I also don’t do the company procurement of aircraft, but our company has bought 320 NEO’s with engines with funky do hickies and blades. So that is all i am talking about. 
Of course i could rabble on about the 186 seat retrofit, new designed seats, sharklets, the fact that the new sharklets bounce light off the glareshield into your face at night time and how they have some funky fix for that.
But we were talking engines and i don’t need to mention those things.
