What is the longest soft golf ball on the market?

I'm looking for the best long distance golf ball, but it has to be soft. It doesn't matter to me or my golf buddies if it's non-conforming-we just want the longest drive we can get.|||Titleist Pro V1 and Pro V1x, costly though.|||Golf Magazine and Golf Digest have both proven that there's only ~5 yards of difference from the softest "tour" ball to the hardest "distance" ball. The only ball that differentiated was the old Nike One Platinum: with a robot swinging 95 mph, it went 231 yards, compared to the average of 255 with the others. When the test went to 105 mph, it's performance became comparable to all the others, however (~285 yards).|||Titleist pro v1 are the longest ball out there that will spin on a green , But give 'titleist nxt tour' a try , it doesn't spin! Therefore longer distance! You won't be able to control your iron shots into the green tho , it just won't stop! little bit cheaper too.|||I'd have to say Titleist pro V1's but more specifically Pro V1x because unlike Pro V1's, it spins a little less. You can also try the Srixon Gold its long as well.
