I wouldn't go out and buy roven to replace the roven you grown out, I would just use the 1708 you already have. If you have the roven you can use it but the biax in the 1708 is stronger than the roven due to the nature of the flat strands. The woven strands are not pulled as tightly as they weave up and down around the 90 degree opposing strands. Plus the glass to weight ratio makes the 1708 much stronger when applied right. I would just build it back with the 1708 by laying a narrow strip in the corners and then a slightly larger one on top and then slightly larger so on and so on until you have plenty of build out and a nice radius in the corners. You don't want a hard 90, you may even want to radius with a filet then build off of that. Also where it cracked all the way threw to the outside or is open to the out side of the hull you will need to feather that back from the outside and then build it back up with some csm so that you can smooth that out. That will prevent the crack from showing up threw your paint work.
