Interesting to see the blades, but I thought that they were also interested in the 'cookie cutter' trailing edges of the cowling, or was that only Rolls Royce?
As for HKGSpotters comment, I don't really think it is neccessary for you to jump all over him like that. Calling someone a troll is not really very nice at all, and just what are you saying about plane spotting? It's my favorite hobby as well, and from what I gather from your post you don't think much of it. That's fine but no need to be rude.
