Dove57, There's a good chance that you will get ten different answers to your question. 74" wing span is a fairly large wing, but I'd be more interested in your estimated weight. Without knowing any more details of your airplane I would suggest two layers of the 4oz. cloth. Make one strip approximately 3" wide, and the other 6" wide.

I'm the odd ball here. I use a layer of 5.7 ounce carbon fiber fabric about 1 inch wider than the fuselage. I cover that with a layer of 3/4 ounce fiberglass cloth . All is done at one time, top and bottom, and vacuum bagged until cured. The carbon is always cut on the bias and the fiberglass cloth is there only to allow me to feather the edge without sanding into the carbon. I have never had a wing fold and I beat the crap out of them.

I use the approx 6" wide automotive stuff you can get in any automotive or big box store auto section. No idea what the weight is, but it is available, cheap, and it works. Wide enough to make the saddle under 'glass (don't try to eat that one) so you don't end up smunching balsa sheeting. Attach with a thing film of spray adhesive, then finish with epoxy. Spackle to fill.
