The Srixon AD333 Tour claims to offer 'tour performance for moderate swing speeds, so given I am neither this could be a tricky review.
However balls should be able to work at all speeds as irons and wedges go slower than drivers, so for most of the bag I should be OK.
This is the third generation of the AD333 Tour and as such it uses the same 3rd Generation Spin Skin coating over a 338 dimple urethane cover that was also on the Srixon AD333 2017 ball launched last year.
This forms part of a 3-piece ball that uses a lower compression 'Energetic Gradient Growth' core that gets firmer as you move out from the centre.
That's how it all works, so how did it perform on GC2? With a 7-iron the spin was indeed up as claimed by around 150 rpm for me, which is fine, but that did hurt the distance a little.
However that is not all bad as with approaches the ball should stop quicker with more control, which is what you want.
With the driver, the core did its job and there was less spin, also as claimed. This time it did help distance and also accuracy as the side spin also drops.
Around the green, the 2018 AD333 Tour feels a little softer than the 2016 version but on chips it performed pretty much the same with mid-level spin control.
Putting was also good with a mid-softness for sound and feel that would give good feedback with most putters and certainly more than the softer Srixon AD333
If the idea is to have a firmer feeling and sounding ball than the AD333 with a bit more control, then Srixon has succeeded with the AD333 Tour. It is about £8 per dozen more, but it is worth the extra and it stacks up pretty well against the competition too.
