I know I'm probably being a bit of a whinger but ,,,,,,,,, I recon the Rev could have had those elastic loops that hold the lines on when it's wound up ???? I had an old Liquid Force bar and lines and I thought the loops were as handy as a hole in the bum .. ???? What do ya's recon ???????
Just go buy some bungy cord and tie a loop to each end of the bar.
They come in handy when you have to do a self rescue or need to carry your kite and bar with the lines still attached.
