I received 2 sleeves of Optic yellow 2 weeks ago. Felt a bit softer than NXT tour S. Carried on full swings similar and a bit more spin around greens. Subtle but better. Played 3 rounds with one. Maybe ill tee them up at Wolfdancer tomorrow. 

I received the Black on Black test balls.

Super soft, high launch, added distance.  What's not to like?  I would switch to this ball in a heart beat. 

Only negative is they do not float.

I got them as well. I have bstone E6 in my profile. These new ones had the spin control of my bstone but had a lot more distance. I cant wait to find out what they are as well Im switching.

I"m down to one ball left, they seem to perform better than the e6 for me...a bit longer, and better control...stop on the green very well, and putt true...if I ever find out what they are, I'll sure buy some...

I have not recieved mine this year? I may go into withdrawals- Have you tried them yet?

plays like a valisety

Mel did you think it was a little softer?

I know Jim, they are tough, I still have all three of mine and yesterday I found one that someone left in a Bunker Now I have 4 :) I do like how they hold the green, but it's early to tell. Up north here the greens are soft and balls stick well.

There are multiple Test bals.  Apparently there are black numbers and dark red numbers, as well as at least one variety of test yellow balls.

I got the white balls with dark red numbers.  I haven't used the NXT Tour-S, but these red numbers have been in the same distance or longer than I was getting with either the NXT Tour and Pro-V1x.  For me, all 3 held greens equally and better than other 2 piece and older 3 piece balls I've used in the past.  On one drive, the Test ball got my best distance for the year.  On a par 5 dogleg, I normally come up 30 yards short of going through the fairway, hoping to get far enough to aim down the fairway w/o cutting the corner..  Through it.  On another, my approach shot is normally a 5 or 6 iron, and I used a PW to get on the green in regulation.  If my ball gets to production - I need to find out which one.

First Tee is geting a donation of all secret stashes (down to my last 3 NXT's) of full sleeves and boxes.  Now if it only came in visible yellow I won't have to spend so much time trying to find them when they go further than I can follow.

Don, same here longest ball I have played and I have played the all

I got the ones with the red numbers.  I can't wait to find out the real name.  Tested the nxt tour S both white and yellow last yeat and was very impressed by the performance.  This new one exceeded my expectation by a long way and I definately want to know what the new test balls are so I can get more in my bag!!!!!!!!!!

No idea what ball it is, but I wish I knew. I would definitely buy them, I really was impressed with them.

 Try out new test balls.Hit all three in round.Average drives about 230 -240 yards.Held the greens good.Ball has soft feel to it.Only problem with balls they cut easy.Overall found balls very good.
