The AD333 Tour features what Srixon call a lower-compression energetic gradient growth core.
They say this core is easier to compress with lower driver spin and more distance on full shots.
We’ve got a 338 speed dimple pattern which is designed to reduce drag.
Srixon AD333 Tour review – The results

I’m mainly looking at driver distance, spin and feel on iron shots and around the greens.
I’m also looking at durability and performance in the wind.
When I hit a good drive, this ball went just as far as I’d expect with a nice strong ball flight. It didn’t seem to spin too much or fly too high with the driver which are both very positive attributes for me.
I was impressed with the spin on mid-iron and full pitching wedge shots.
I hit one pitching wedge from 125 yards which stopped dead when it landed and another half shot with the pitching wedge which spun backwards a few feet.

When chipping around the greens, this ball didn’t feel as soft as the Z-Star.
There is a noticeable difference in feel to the regular AD333 which is much clickier. The AD333 Tour has a premium feel when chipping and it allows you to be aggressive with your wedge shots.
When putting, I felt the side-stamp was really useful lining up. The writing is a bit longer than the regular AD333, obviously, and it it very useful for lining up putts. I wouldn’t feel the need to draw a line on this ball.
It was a fairly windy day when we tested this ball but the performance in the wind seemed very solid.
My playing partners were using more premium balls than I was and it was not noticeable that my ball was being more effected in the wind than theirs.

From a durability point of view, I noticed a bit of scuffing after 9 holes. But this ball lasted me from the third (lost my tee shot on the 2nd) to the 18th.
I’m not sure a top-price premium ball would have suffered quite as much.

Srixon AD333 Tour review – NCG verdict
This ball offered exactly what I expected – a solid all-round performance with a bit more spin than I’d expect from the regular AD333.
I think it’s a very competitive product at the £30 price point. The extra £10 is definitely noticeable when it comes to spin and feel with iron shots and around the greens.
The one area where I didn’t think it performed quite as well at the £45-£50 balls was on durability. The cover did seem to suffer a bit of damage.
But I’m really struggling to find any areas where actual performance is suffering for not spending the extra £20.
Maybe on feel around the greens if I’m being really picky.
If you’re an AD333 user, looking to improve, and feel like you could benefit from a bit more control with iron and wedge shots then it could be well worth moving up to the AD333 Tour.
