I got to go nanos because their strong penetration is insane blew through 1/2 of the targets on a 3-d course yesterday. they arn't as heavy as the bemans. bemans are made by easton but that don't mean their as good as other arrows easton makes. I would put the nano's in the same class as A/C/C as far as straightness & accuracy but lot stronger. THEY LOOK COOL also
