that is the straightest I have ever seen someone cut the stringers open, holy cow. I used a peice of 2" dyvinacell to raise my stringers on the third one , number one and two I just rip strips of marine plywood and glued and screwed them together then glasses them to the stringers. I think 1 sheet of 3/4 marine ply ($120) will do all the stringers. if memory serves me they are 3 " wide. I think I stack 3 pieces on top of each other. dont waste your time or money on the hard foam from homey depot it has no strength at all.
