The Kastaplast Falk is a precision-crafted distance driver with a rare combination of moderate speed and surprisingly shallow fade—its -2 turn rating creates a wicked understable character that rewards skillful release but can be unpredictable in stronger arms. When released perfectly, the Falk explodes forward with 9 units of raw power and a gentle 1 degree fade, making it perfect for players seeking a predictable yet challenging workhorse. Despite its modest glide numbers, the Falk generates remarkable distance through sheer speed retention and controlled collapse.
