Up until now my main interaction with golf balls was simply trying to hit one.  Now I'm starting to be able to feel the difference between balls.  I'm a fairly high handicap golfer who has been playing for 2 years.  I went to all Titleist clubs last year and am completely happy with them.  
My quandary- In addition to the ProV1 and ProV1X Titleist has released a new DT Trusoft, Velocity, TourSoft and AVX.
Other than buying multiple sleeves of each and doing a massive cross-comparison - how do I figure out which works best for me? I am hoping that a ball fitting event happens near me and I can get a spot in it.
Any other thoughts?
Abby L- the chart of ProV1 vs ProV1X and AVX was great.  Is there such a beast for all balls?
