Need help to repair tear mylar, any suggestions?

Change the nose and replace the center Dacron piece by a larger one.
Agreed. Replace the nose material, put a wider section of dacron as the inner layer.
If you don't like the idea of a wider dacron section, you can use a triangle of ripstop in front and behind the torn section (sandwich the torn section). Sew the ripstop with a few parallel seams at right angles to the spine line - sort of like the nose of a Widowmaker or Sea Devil.
Thanks Kevin and everyone.
I like the idea of Lam's few layers of ripstop at the nose area, but I never build a kite before. Do I have to sew new dacron/nose material for the nose or can I reuse the the current one.
I do not want to put too much weight on the nose since this is the Double Zero kite.
