glassing and tape?

I hope to glass the bottom of my micro this weekend.
I was planning on taping the edges(4oz biaxel) and then laying down
the dynel(6oz) over top of that. Is that the proper order? I want
both durablity and i'd like it to be easy to fair it up.
Also what is the most i can round the chines and transoms without
weakening the side to bottom joint?
Thanks,
Jason

PS i've gone with two layers of 3/8 on the bottom.
