Heads Up Matches

[JABoyd]

I play $20 heads up matches online. Something I encounter a lot are people running their mouths and eventually saying 'If you're so good why are you at the $20 tables and not the $100 tables?' I think of it as minimizing variance. I feel the skill level is horrible in the $5s and $10s, weak in the $20s, and it increases in the $30s, $50s, and $100s. Therefore I play 3 $20 matches at a time (with a winning percentage of over 65%) instead of 1 or 2 $100 matches at a time. Am I right in this theory??
