As the name implies, the UltiSoft is the softest ball in Srixon's line with a compression of 40, which is 20 less than the Srixon Soft Feel 2018 golf ball.
Softness is what this ball is about and it is targeted at those with mid to slow swing speeds who want a ball to go straight.
Soft golf balls are generally low spin balls too and the UltiSoft is no exception, as this makes them a little straighter as they don't have as much sidespin when you cut the pants off them with your driver.
The 2-piece ball continues with the same Energetic Gradient Growth core as before that gets firmer as you move out from the centre.
The ionomer cover is 1.45mm thinner than on the previous Srixon UltiSoft 2016 golf ball with a different blend that uses Tefabloc HR+ this time around.
It now has 338 dimples, up 14 on the previous 324, with a new design in order to improve the launch and reduce drag.
The sidestamp is also a little different as the two lines are not touching the arrow now, so you are going to have to be pretty eagle-eyed to spot a 2018 ball from a 2016 one.
There is also a choice of pink for the ladies and yellow for the men who want to brighten up their lives.
However softness is what this ball is all about and right through the bag you could hear and feel this. Even with a metal faced putter on and around the greens it would not even bother someone putting with a migraine and with a soft insert putter it would get Quiet Mark approval from the Noise Abatement Society.
This is not a bad thing, but I prefer to hear sound when putting as that will help you judge the feel.
Soft balls will also compress more at higher swing speeds as I can demonstrate when I took the UltiSoft 2018 on GC2 against the previous model and other 2-piece balls from Srixon.
With the 7-iron there was very little difference between the new model and the old one, but as you can see, the Soft Feel with it's firmer compression went further for me and then the even firmer Srixon AD333 2017 golf ball performed the best as the ball speed was retained better.
The same thing occurred with my driver at around 100 mph swing speed, and it is really down to the lower ball speed that comes from having a softer core at my swing speed.
That does not make it a bad ball, but you need to be clear on what the differences are with soft balls versus firmer versions, especially when the price is as competitive as the UltiSoft, as you will get what you pay for.
Soft balls will spin less and that may have an effect on how your ball reacts on the green, so test it out against your usual ball on the course and see if the make up of the UltiSoft makes your heart go all gooey.
