The STX Duel 3 lacrosse head is redesigned to be even better. Our Pro's feel that the STX Duel 3 earns the title as one of the best lacrosse face-off, stay-on midfielder lacrosse heads because it now features Reflex which is a new material that holds its shape and keeps you on the field longer. The new Speed Scoop provides for faster ground ball play, since it contains faceoff flex. Get it custom strung by our Pro's and you will see the advantage. This head has a throat plug and will only work on hollow shafts.
