Im no ball motion expert, but lots of 9 pins and ringing 10s is too much angle/drive.
Along with the above, I'd also suggest this, based on my use of 14s, along with several drillings over the past 4 years or so:
Pins over drillings tend, for me, (also old and also lower ball speed with higher revs) tend to go too long and have very late ball reactions, despite surface changes. For the 95% case, I tend to have better ball reactions with pins no higher than in either ring finger hole, but generally just below the level of the fingers. Remember that 14 lb. balls tend to have higher RGs to begin with, besides their lower ball weight allowing you to throw them faster than your old 15s. You need to balance ideas, like this, with coverstock strength and surface for the amount of oil you bowl on.
On top of all this, you need to hit the dry at the right angle and at the right spot.
All those leaves: 4 pins, weak and ringing 10 pins, 9 pins all point to either you're playing the wrong line or you're using the wrong ball/drilling/surface. I'm surprised you haven't also been leaving some pocket 7-10s.
