Use HD rubber underlayment and just cut the shingles for a closed valley.

Gurus:

This summer we plan to replace our 24 year old shingled roof with
long-lasting dimensional shingles.

Contractors are pushing two schools of thought for the valleys.
1. Use pre-painted metal flashing. (This is what we have now.)
2. Use close cut shingles in the valley.

Which process would you recommend for the longest-lasting roof?

Thanks for your thoughts.
