I have also had exactly one game where I used the Taiga for red along with Heritage Druid mana to cast Ruric Thar.
I know that's anecdotal, and small sample size, etc., but in my experience it has basically come down to personal preference; would you rather be greedy by running fewer basics, or by relying on creatures to provide your off-color?
