I have a chance to get a Special Agent or 2nd Dimension. I can get the SA for $58 shipped and the 2D for $70 shipped. I know I don't need either one. I used to have a SA that I was starting to love, but cracked half way around the ball. Again, I don't need either but I really liked the how smooth, strong, and predictable my SA was. However, the 2D looks nice too. Looks like a nice strong pearl, but I don't know. Thoughts?
