The idea that certain balls are better or made for slow swing speeds haven't really held up under testing from what i've read. Its more marketing myth than anything in an attempt to make market segmentation easier (or at least thats my opinion).
Check out this article from MyGolfSpy. Particularly points 3 and 4 in the introduction. Then take a look at the data for balls at 85 mph swing speeds.
Generally speaking, golf balls marketed to slower swing speed golfers are lower compression balls. And lower compression balls are generally slower in ball speed, resulting in less distance. And if you play balls that don't have a soft urethane cover, you will lose spin around the greens. So a ball like Chrome Supersoft, you will lose distance off the tee and spin around the green versus something like a Pro V1x. In fact, that article recommends the Pro V1x as the best ball for distance for slower swing speeds, which runs contrary to almost everything you see related to marketing for the Pro V1x.
It looks like price is a consideration to you and how much that difference in performance is worth to you is entirely up to you. There are some great balls comparable in price to the supersoft (or a little more expensive) that should give better performance at any swing speed, such as the Maxfli Tour or Snell MTB or Kirkland balls.

I think he will, Finau and his coach just talked on their podcast on July 31st about how their plan is that he is now starting to train more speed in practice with the goal to take more fuller swings and let some go when the hole presents him with the opportunity to do so in tournaments.
And Finau also made it very clear in that episode that he wanted to be the first guy to have a 200mph ball speed in a tournament on the PGA tour.
In case anyone is interested, his podcast is called "Let's Get It" and the episode is called "Pushing the Limits of Ball Speed on TOUR"
I can agree with that. I just feel like it is more forced with Bryson. Finau looks more relaxed and in control. I just brought up the numbers because Bryson getting over 200 was all the talk not long ago.
I would recommend trying them. It really is up to you to find a ball you are comfortable with. I’ve not noticed much performance difference in balls except for maybe Pinnacles, which feel rock hard to me. I’m not sure if I believe in the ‘swing speed’ marketing approach. They don’t really show much data to support it.
