Test balls

I have been trying to get my hands on these Test Balls for the new 2013 Pro V1 line but can't seem to figure out who to contact to see how I can get some... I tested the last Prototype balls and was curious if any of you Titleist members knew who to contact for some test sleeves ??? Thanks 

Wait until February and you can test as many as want;)

i've tested the new prov1x balls ilike that i can controll the pro v1 better. the new ball is a little hard to stop

Any idea how the new pro v1s are different than the 2011 model?
