I'm also getting one basically for the challenge of ultra-wide. I read through a few articles online (including the Ken Rockwell one) and everywhere I go people say you have to get close, so we'll see how close I can get.
I also think keeping my shadow out of the pic might be a challenge but we'll see.
I think I will be investing in a GND kit once the weather clears. I have seen some amazing pics in this thread: https://photography-on-the.net/forum/showthread.php?t=224448
