Two Canons when shooting sports

I almost always use both my Canon 50D (with a 70-200mm f2.8 lens hanging on a strap) and my Canon 7D (on a monopod with a 300mm f2.8 lens) when shootong outdoor sports.  This works great for soccer especially...the big lens captures the action on the far end of the field while the 70-200 allows me to shoot the closer side of the field.
