I know this is weird, but in my inventory of golf balls I have ProV1, ProV1x, NXT Tour, and NXT Tour S.  I've been playing a dozen yellow NXT Tour S' my mother-in-law gave me for XMAS two years ago, and am loving them right now.  I love the soft feel.  I'm pretty sure I'm not hitting it further than with the ProV1, but love the lower flight, and the super-soft feel around the green and especially for putting.  I can just take a whack at it with my putter, and the distance is dead on.  I just need to worry about the line.  Now I just need to decide what happens when I lose the last one.  Do I go buy used NTX Tour S balls, or do I give the Tour Softs a try.  Big decisions.
