I am considering buying the dubby double sled.Those of you who have the dubby after setting up sled how easy is it to set for 90 or 45 or any angle.For repeatable cut lenghts are you satisfied with the results.I am not interested in building my own but I do want try and avoid any buyers remorse as we all do.I have looked at the inline site and I have talked to Jerry,but real field use and comments cannot be beat.Thanks in advance for any replies
