Those are the same type of plays I'm finding as well. I think I've gotten 2 or 3 2x at or near the break even on their own.
I've been using the 2x as a type of loss rebate so I don't get stuck chasing a pure 3x. I want a little more than 3% to chase a 1 in 3000 shot... It's a little better if it's a 3x or 4x play.
