Mine vary from 5 to 8 ft. I never deploy my noodles in open water. Always in coves and mouth of creeks. I like to set mine so they will drift across to a wind blown bank. This way they cover a lot of territory. Also makes them easier to find. I always try to keep them in sight while I fish other ways.
Infidel and proud of it.
From Genesis: "And God promised men that good and obedient wives would be found in all corners of the earth."
Then He made the earth round...and He laughed and laughed and laughed!
