A 9-speed MVP driver from the original distance lineup, positioned between the Tesla (more stable) and Impulse (more understable). For moderate arms it flies fairly neutral with a modest finish; power throwers use it for hyzer flips and turnover distance. Gives easy straight distance without full distance-driver speed.
