Swirl S-Line PD Last Howl Colten Montgomery Signature SeriesThe Discmania Last Howl PD is the latest Signature Series disc for Colton Montgomery. The Swirl S Line plastic looks great when combined with this Discmania staple. As always, the PD can be a do it all type driver. The PD can handle windy conditions, strong side arm throws, big hyzers, and long flex shots. This run is relatively flat and on the gummy side. It's been said this is one of the more straighter PDs to date.
