A .350 Spine is stiffer than a .400. But depending on the manufacturer those numbers do not mean the same. Carbon Express does not use the same rating as most others do. Although they have a table to convert their numbers.

More mass at the end of an arrow will make it virtually stiffer while mroe mass at the front of an arrow will make it less stiff. So 4 vanes make a stiffer arrow than 3 light ones. And so on.
