Help me understand these driver adjustment results and possible shaft selection

[Fromthecoast]

Lately I have been playing a draw off most every tee box. Sometimes this is turning into a big hook and landing me OB left which is something I would like to eliminate. Recently I was at Dick's hitting on the simulator because it was a rainy day and I could not get to the range. I was hitting a draw with my Cleveland Classic Custom XL 10.5 with the JDL6 Stiff Shaft but not near as much left as I was with my Cobra Amp Cell with the Prolaunch Red Stiff (also set at 10.5). I started playing with the adjusment and thought I was opening the driver. I started hitting a high cut that instantly was much more on line than my other shots although it was ballooning some and distance did drop off. I was launching anywhere from 15-18 degrees and I typically play the ball forward and hit with a positive angle of attack. When we finished I realize that instead of opening, I had actually closed the clubface -1.5* and the loft was now 11.5. I was seeing total drives at that time around 255-265 with minimal roll and the decent was definitely steep.

I'm somewhat confused as I would not have thought that a closed clubface would make me cut the ball more, but those were the results that I was getting. What does that indicate about my swing path? I thought I my path was relatively down the line or just slightly in to out, but the changes I was seeing makes me think differently. Another point of reference, I was just recently custom fit to C Taper Stiff Iron Shafts by the Mizuno Swing Optimizer with positive results. My swing speed was pretty consistently 102 with some jaunts up to 105 when I was hitting the driver on the simulator at Dick's. My longest drives were with the Amp Cell at 275 or more but were all WAY left. I've also recently played with a X Hot Driver 10.5 Standard Setting with a Stiff Black Tie and still hit some hooks into the trees. Obviously I can improve on my swing but I am also curious to what I was seeing with the change to a closed face. Seemed different than what would be expected.

Would indicate the path is down and across.

Was the contact mostly in the center or towards the heel?

Not sure. I'm going to pick up some impact tape for another range session to find out. Most of my misses seem to be vertical rather than end to end with occasional misses on the toe of the club.
