those look good too. wich ones cheaper? you should deffinently go with witch ever one your most comfortable with. and that is a lot of wieght. you could cut half inch starboard to 2 inch strips and mount them on 90's, like a ladder, then mount ur starboard plate to them. would be hell for stout then! that second set looks like it might wanna act like a hinge and let the ends swing towards each other as the strbrd tries to bend in the middle.
