I went to a demo day today and loved the 913f 13.5 with the 72 S+ X-flex.  The ball flight was slightly high/spinny, but the D+82 X felt too boardy/not responsive enought...I was thinking of ordering the S+ 82 X, but I don't want to change the swingweight.  I tried many other shafts with heavier weights but I felt I had to work a little harder to get back to the ball.  Should I get the 72 tipped to bring down the ball some or go to the heavier shaft...How much will the tipping bring down the ball?  Thanks in advance for any help you can offer.
