Thanks for giving the Project (a) a try and hopefully this helps:
Project (a) 2014-2015 (white only, sidestamp: Project (a), (a) in red): 85 compression ball (60comp core) designed for high spin for am’s into and around the green, also had higher iron/driver spin.
Project (a) 2016-2017 (white and yellow, sidestamp: Project (a), (a) in black): 70 compression ball (40comp core) designed to maintain greenside spin but with softer feel and slightly less iron/driver spin.
Project (a) 2018-2019 (white and yellow, sidestamp: <(a)> in red): 70 compression ball (35comp core), new material between core/cover, new cover and dimple pattern. Designed to maintain greenside spin and soft feel but significantly reduce driver/iron spin as well as improved aerodynamics for more distance and better performance in windy conditions.
Project (a) 2020? would love to hear your feedback on the 2018 version so we can incorporate into our development cycles.
As a project (a) fan who used every version, this is very welcome to see Tmag listening to users directly.
To me, 2016 version is very good but feels bit EMPTY when hit. 2018ver, so far has been better in terms of that. but I only played 2 rounds with it. Will report back.
For 2020 version, I don't agree that you need to keep the launch lower. This is geared for amateurs and they need the launch.
