The Discraft Swirly ESP Undertaker carries Ben Callaway's Tour Series stamp on a moderately overstable driver that plays like a straighter, farther flying Stalker. Every purchase supports Callaway directly, and the swirl finish means the disc in your hand is one of a kind.

Flight Numbers: 9 / 5 / -1 / 2

Swirly ESP is Discraft's grippy premium blend, honest in the hand and durable enough to hold this mold's overstable flight for years of regular play. It stays predictable release after release, which matters on a driver that rewards a clean, consistent throw.

Thrown flat it holds a straight line with a forward, predictable fade at the end, and you can dial that fade up or down depending on how much power and angle you put into the release. It excels on pure hyzer shots and works as a real workhorse for anything past 250 feet where placement matters more than raw distance. It handles a headwind well and is one of the more comfortable forehand options in Discraft's overstable lineup, though it can get touchy without solid form, so it rewards intermediate and advanced arms more than a true beginner stepping up from a midrange.
