I currently game the Maxfli 2019 Tour balls (matte green), but I recently noticed that my local GG is carrying the 2021 version (gloss white only, unfortunately), so I picked up a box for around $35 and gave them a try yesterday. Overall I couldn't tell much of a difference (which is a good thing IMO) - I did hit a couple of longer drives then I'm used to hitting, and I'm not good enough yet to really be focusing on spin around the greens, but overall I was happy with how they performed. I'll probably still buy the 2019's for as long as they are in stock (I think GG currently has a deal where you can get 2 boxes for $55), but I also think I'll be just fine when I inevitably have to move to the 2021's. Now if only they could add more colors.....
