Hi everyone, I have a Levitator and am looking for some advice when it comes to oars. Should I go with 9 or 9 1/2 ft oars? I know that is all up to the person who is rowing. I have 8ft oars now and I think that they will be to small. Also, should I go with the one piece or two piece breakdown type? Keep in mind that I will need to fit them into a 170 or 185. Thanks
