Can you guys explain to me what is happening with my swing when almost all of my driver face marks are now located off center from the sweet spot and more towards the hozel side of the face? I applied some spray to my new driver and 9/10 shots made a mark off center almost inline with the hozel. My swing has not changed but my driver was upgraded from the 910 to the 915. The 915 is heavier than my old 910 im finding it a little harder to swing freely. Both drivers have stiff shafts.
When I had the 910 my drives where really good, but now ive lost distance with the 915 and the flight path is very random. Remember my swing is still the same. Im stumped...!!!
