I resemble that remark.
Most of my bets are + odds, because underdog bets earn greater reward points at some of the US-legal books. And some of the promos disallow deeply minus odds.
It makes sense that a +1000 is more popular than a -2000, for the same reason that Vegas locals drive to Primm to buy lottery tickets.
That would explain why the Super Bowl "no safety" would often be a good bet. I heard about that one from Wizard, although I assume redietz thought of it first.
