Unhappy To Flash or not to Flash

I am about to reroof my home due to Huricane Francess. I am planning on tearing off old shingles down to the plywood. I have one set of valeys that meet at a peak for a total of about 22 feet 11 feet per side. I am planning on using the Polystick TU peel and stick material for underlayment in the valleys. I have the material, primer and adhesive and have been reading the literature. I have come across some contradictory information, from different sources.
My question:
Using the Polystick material under the felt, should I still use a metal flashing over the felt or is the waterproof Peel and stick sufficient. I am planning on using the Closed, half laced method to shingling. I am also wondering if this will cause too much of a bulge using arcitectural shingles for this approach. Should I use W-Flashing and open flashing for less layers to avoid unattractive bulges?
