I have some dualies, but no 4-liners. A good friend of mine is Joel Schultz, he is one of the best kitemakers in the world. Beautiful Evil, a 4 line dragon kite, is modeled after the Rev. He quit designing a couple of years ago, but his kites won the championships for a few years in the late 90s, dual line and fighter. I will see if I have any pics.
Here are a couple of single liners of Joel's that I have:
