24 32 would get a fella up most hills i reckon if not just walk.
Yup, low gears and a triple is nice to have. You're right about the Tiagra 50/39/xx on a tourer, I had it in my hand and made the best. If I was building up new I'd go for a mountain triple, 48/36/22 and a 14~30 cassette. Key points; triple, start the cassette at 14T and enjoy nice, tight steps.
