But they do recommend heavier arrows. AMO - now the ATA - has a recommended minimum arrow weight chart. For instance, with a speed cam at 70 pounds draw and 30" draw length, the recommended arrow weight is 487 grains. They go down to 5 grains per pound on their warranties but, that's only a warranty, not a recommendation.

So I asked google, this is it's page. Scrool to the bottom, it's Bowtecs link. It reads something like "a minumum of 5 grns.".
