Ah that makes more sense now.
The problem with throwing money at a scope for HFT is that you might end up making it harder for yourself. Buying the absolute best might mean everything from 10 to 40 yards is perfectly clear, and you lose one of the main range finding methods (parallax/scope blur)

The MTC viper connect 3-12x32 has a good following. Or a little Leupold if you can find one. I'm sure both of those have been used to win championships. Maybe a March if you want to go really high end, but then you might end up with that amazing depth of field and harder range finding
