For The Love Of Port

aside from dry whites, can you recommend drier Reserves or even LBVs?

With red's the difference between sweet and slightly drier profiles is not very much. Dow's tends to be on the very slightly drier style so you can try their LBV's and Reserves.

Quinta do Infantado is known for a drier style. I like their products on the lower end of spectrum actually. Never had their higher offerings.
