Since I've done the plywood leading edge "mod" a few days ago I think about the transition from the plywood to the ribs.
There are serveral options and opinions - I'd like to hear yours. If you have some pictures, please attach them, too.
Possibility a) Just leave it with a sharp edge of 1/16" and to the first stich 1" after the LE. (Has been done several times, even Skip Stewards Prometeus is build this way)
Possibility b) Make a smooth transition of ~1" from leading edge to the ribs. Will result in the same profile as a) but with a fully glued fabric and additional support for the ribs.
Possibility c) Make a bigger transition using plywood or putty, such as used here and recommended if you build a Pitts S12: http://www.2wings.com/m12/log/15-3/150809_123026.html
Possibility d) Cover all the ribs and trailing edge with cap strips. Will result in a perfect shape, but add some weight. Additionally I would have a 1/8" thicker trailing edge which might affect my ailerons?!
Hope to get some ideas from the more experienced builders here. Thank you in advance, guys!
