Catalyst is an understable high speed distance driver.

The Catalyst is a perfect starter for big distance. Its stability profile lends itself to being incredibly useful even when underpowered. Catalyst is similar to a longer Wave. High power throwers will be able to control rollers, sky anhyzers, and tight turns, while average to low power players will get easy distance with great glide, and a power responsive amount of turn-to-straight. The Catalyst is molded with the same core and nice even dome as the Octane, yielding extra glide for maximum distance shots.

Shipping will be in a padded envelope.
