Simplicity,very easy to adjust,great accessories for adjustments, plus met EJ at 2010 locust fork races in bama, after i had lost my mother to cancer was having a lot of problems trying to find people to help me with kayaking, i was really bitter at that time, over my mother passing so quickly,n having so many problems in my life. he had a sympathetic ear n listened to me, n even signed a t-shirt for me with the words ( just go for it ). anyway after that, i went to the NOC fest and bought my first Jackson a 2010 Fun, n got my picture taken with EJ on yaws website, very cool, my mother would be proud of me. Now i will only buy a JK because of that. THNX EJ
