Try patching them. It works wonders. Dingo made a good tut showing how to do so.
Trust me, I did try patching (MariokartN's method without DB 2.0) a lot of times and it didn't work.
I have a LOT to do with my link character still, but the most parts of her she's pretty much done =3 I went ahead and used the polygon deleater to get rid of the ones I couldn't vertex out.
