Is the variance in tournaments too unpredictable if you only play tourneys to build your bankroll?

[Bawse]

I think if you properly schedule your games while having discipline with firm bankroll management, and not making key mistakes. It's possible to consistently grow your bankroll grinding only tournaments. I don't play anything, but tournaments. However most the tourneys I've been playing don't reach more than a few tables.

How about you? Thoughts?
