Rubicon, You may also want to try Ironmind magazine if you don't already know about it.
it is published 4 times per year. and has a lot of articles of strongman conmtest and how they train. If you get your hand on an issue look in the classifieds. I recall adds for a magazine by Magnus Ver Magnuson. Don;t know if it is still around.
I also recall Gary Taylor having an add for his shoulder routine ( 500 LB push press !)
