3x5 or 3x6 can provide a wide range of useful cogs with some
surprisingly close ratios.

At the cost of going to a triple, which is going to be more finicky about
shifting than a double.

My 30-40-50 Racing-T setup shifted faster and more smoothly than the 34-50 FSA
compact + Campagnolo compact front derailleur I replaced it with. I think the
smaller difference in chain rings helped.

I could also use all 8 cogs off any ring (about 4 gears of overlap with
the adjacent ring) without rubbing.

Before I shimmed the compact chain rings, I couldn't use the two small
cogs (one cog overlap, lots of slow ring changes). A little spacing fixed that
but upshifts to the big-ring are a little worse. Yuck.
