I've been looking at the 712 CB irons for a while now.  I've recently adjusted my swing and am launching the ball higher than I'd like.  The last time I hit the 712 CB demo 6 iron at my local shop, I was launching the ball in the 18 degree range.  I've been hitting the +1/2" DG S300 shaft in the demo.  I don't mind hitting the ball that high with 3-6 iron, but when I get in the scoring range, I'd like to keep the ball down.  In your opinion, which would be a better solution to hitting the ball so high with scoring irons:  DG Tour Issue shaft  OR get the 712 MB in the 7 iron - PW with DG S300?  Any advice you could set me up with would be fantastic!

Thanks,

Ben
