I only play mobile and this is a very interesting post! The 307yds displayed by the driver is a dead giveaway of apparel bonuses at work. With a tailwind like that I've seen players hit huge drives (350+) with no roll while playing coin matches.
I have never seen apparel bonuses work for me, though, while playing clash rounds or tournament rounds. Having said that, I don't trust the apparel on mobile and I'm not a fan. With all the bugs that remain, and the ones that are created with updates, it's no wonder apparel bonuses creep in to other game formats.
Maybe WGT will "fix" the missing decimals on the greens and it will create a bug that makes all the new apparel disappear ;-)
Apparel on mobile: back to basics!
