You shouldnt use 1-6, 1-7, 3-1 & 3-2 because the misalignment of the chain is bad for the system. Shifting onto a different chainring is the equivalent to changing several gears at the back. So carry on as you are, using the middle chainring most of the time. If you come to a sudden uphill, dropping down into the small chainring reduces the number of downshifts you will have to make. Similarly if you have a strong tailwind or are in 2-6 or 2-7 at the start of a long downhill shift up to the big chainring.
