I'd always rather have the range than closer spacing but each to their own. I've toured on 50/34 12-28 and although could have done with about 3 extra gears at the bottom I used all the gears at the top multiple times. But then I can't help myself on a descent whatever type of riding I'm doing.
48/32 with 11-36 sounds like a great option, or yeah a triple with lowest granny ring you can find as others have said.
Nah, considering that this is a touring bike, I believed 46/34 with 11-36 would be apt.
Or even get those 48/32 chainset from Spa Cycles.
