The high face shot will take spin off the ball and might result in more distance for a player that spins the driver too much.

with my 909 and this driver though my solid shots or relativly lower almost knuckel balls

Center face contact is where you should get optimum launch and spin if the driver fits your swing, and of course the ball.

Your description sounds more like low on the face contact, low launch but with increased spin not knuckle ball(no spin).

What you may be doing is hitting with a descending blow, like you would with an iron.

Worth an investment in contact stickers next time you play.    You'll see excactly where you are hitting the face.

Well i know im hitting it high and center from the small ball scuff on the club
