I would get all the same lenght.This way when your scanning the tips your eyes never have to refocus. If you want 12ft you can get 4 silstar rods for 50.00. Ive used them a few years before i went to 14ft. Now I have BnM pro staff trollers. I now use the silstars for cranks. Check the pro classifieds The Crappie Hot Spot had them 20% off. Nice guy to deal with. Merry Christmas
