Just a fair warning, this might be a bit of a longer post

So lately in league, as the season winds down, the house is preparing for the summer and putting out less volume of oil.  Generally, I use an OOB Ebonite Mission or a 1500 polished Storm Gravity Shift.  Now that the volume is down, I need to use something less aggressive so I went into the archives and found my old Storm Pyro.  

I had the ball at 2000 Abralon with some polish on it, so I tried it at that just to see how it reacted.  The ball read the lane well, made a good move to the pocket, but carry was almost negative  These first three games I shot a 540, but was consistent in repeating shots and hitting the pocket.  I had a clean 203 and a 196 with one open, so it wasn't like I was bowling horribly.  But I can safely say I left about 8 or 9 ten pins in the 3 games, and a seven pin.  

The ball was breaking to the pocket a bit sharply, and also going a bit long at times, so I figured the polish was really hurting the reaction.  So I hit it with a 2000 pad, then a 4000 pad.  Come my second set with the ball - the reaction was definitely better the first 15 frames.  Then as the set went on, things got pretty ugly.  The 10 pins came back, but not as frequently.  But the 7 pins, and 8 pins, were nasty and everywhere.  So I took it upon myself to experiment the last 15 frames with different ways to release the ball, and the few wrist position changes that I know work well for my game.

I then took particular notice that the ball seemed to exaggerate the release and wrist changes I was trying.  Like, my asymmetric gear has noticeable differences when I go from release style to release style.  But the Pyro was almost melodramatic, for lack of a better word.  If I tried to let it down earlier, it read a lot earlier.  If I tried to push it down the lane further, it missed the breakpoint.  It was confusing to say the least.  

Also - this isn't the first time I've had trouble with symmetric gear this season.  The ONLY symmetric ball that I've had any success with the past 3 months has been my Storm Dimension.  My Pyro and T-Road Pearl are just way too unpredictable for me.

My questions are:
1) Do symmetric cores react more strongly to release changes than asymmetric cores?  
2) With my two experiences with two different surfaces, would another surface change help carry my corners and blend the over/under?
3) My game has changed a lot this season.  Is it possible my game doesn't like the way this ball is drilled?
4) What's your favorite food?

Again, sorry about the long-winded post.  But thanks in advance for the help!
