I would go with 9 footers!
The oar length formula is: 1/2 the distance between the oarlocks x3 + 6 inches.The stock oars I received for the Predator are just 5 feet. I am contemplating an oar upgrade to a longer oar. Sure would appreciate any advice anyone has on size, type, and or brand. If I went the composite route is NFO the only source of pre drilled composite oars?
