I heard about this change earlier this year. I went through Wood Badge back in 1986 - SC308. I was asked to go back on staff, but could not due to my work schedule at that time. Since then, I have been on staff of almost every other Cub Scout and Boy Scout course. My wife and I have been Cub Scout Roundtable commissioners for about 8 years and have received the District Award of Merit and the Silver Beaver.
I have heard both sides of the argument on which Wood Badge is better. I personally believe that the old course needed to be brought up to speed and think the new course is a good thing and is going in the right direction. However, I am now in a posistion where I can staff a course, but cannot unless I go through it again! To me, I find it insulting. I am good enough for all the other things in the council, but not Wood Badge staff. I have heard that there are those that wanted to move the "old timers" out, and believe this may be one tool they are using.
I don't know why the powers that be doesn't think someone who has not been through the new course cannot teach the new methods. After all, the staffers on the first courses went through the old course.
