1) kattydid (most different colours I've seen on a nose, I like it!)
2) Double Down (I like the paint under the cowling and scoop, it's very different compared to most 51s I've ever seen in that aspect).
3) Grim Reaper (because the name is big and bold and awesome and it also has a cool checkered nose)
All are great but these are my favorites. Amazing work Oboe!
