I bought the double bladed ones,dont remember the name there are yellow if that helps. I run four lines off both sides and they are terrible! I have a 22ft boat with the mast mounted on the bow,4ft mast I run the boards out 40ft and the darn things are 10ft behind the boat. To turn around you almost need the hole lake. If I run deep divers and there is about two foot rollers the line catches the rollers and some times flips the boards, that really rattles my chain! I see other guys with double boards they have no problems,boards are almost strait out from their boat with more lines out than I have. I would buy skipper9 boards or make my own, if you can turn around on a dime with those other boards. I'm very disapointed with mine. I paid well over 100$ for mine I would put another 30-40 bucks out to have a real set of boards!
