Its all about what you are trying to view - with the 170 degree angle it does not miss much. If you are going to be doing shots of the camera back at you (not recommended in the Greenroom

) make sure you stick to the side of the stringer so your legs and body do not get in the way as much. If you are a natural stick it a few inches to the right of the stringer and vice versa if you are a goofy. Always use a safety line as well. I will post you a pic of my set up tom evening.
