I don't know how much truth there is in it and I can't remember the author's name or link, but I read that it's better for the shoulders and rotator cuffs and such to have a ratio of 3:1 on Db v Bb bench press.
So, for every 3 workouts that you do Db bench press there should only be 1 workout that focusses on Bb bench press.
I think it was 3:1, not 4:1 but I could be wrong.
