With its big sweetspot and comfortable response, the Donnay Formula OS EXT is a versatile frame with on-demand power. Beginners and intermediates with compact to medium strokes will have no problem achieving depth. Those with longer strokes will appreciate the open pattern, allowing them to tame the power with spin. Doubles players will appreciate both the stability on block volleys and the power on put aways. On serves, the extra length (27.25 inches) makes for greater power and spin. All in all, this is a very promising oversize frame that should work very well for a wide variety of players.
