I implemented the changes couple of weeks ago. So far it is going well.
Not hit a penalty (yet ~~ ) Google crawls have trippled, site visits are up.
There is a surge in duplicate title tags but I presume this will clear as the 301s are filtered through.
Bing is having an issue with a small handful of the pages in that it doesn't find the correct sport but that's not worth bothering with.
Thanks to all who helped me with this.
