I have 2 on my boat. Plus 2 big jon captain pacs. Had no problems with them during the Winni. derby. The only difference I could see is I think the rod holders have more positions on the Big Jon's.
thanks, i ordered the fishlander. they say it will mount to the pad that the big jon now sits on, which means i may be able to use the rod holder from the big jon as well. i may mount the old one on the back corner of the boat or just keep it for parts for its twin.
