First things first... S/A/Y stands for Silver / Aqua / Yellow...
Just like I mentioned in the Hustle™ P/R/O review it was performance and looks that were the driving force behind these new HP1™ balls. The new Hustle™ Core does not disappoint and in fact it could've easily been sold at the HP2™ level. Yes folks it performs that well and because we wanted more we dropped it into the HP1 slot. It's ok... you can thank us later.
And if you are wondering about the cover... yes this features the brand new Psyched™ Coverstock which is made up of 2 parts pearl and 1 part solid thus providing a little more length that the Stoked™ Cover found on the Hustle P/R/O. Now I am not saying it is drastically different... I am saying this cover is different enough in the fact if you need more length you choose this one... if you want earlier and smoother then I definitely advise the P/R/O.
I think that about covers it... new core... new cover... and of course the idea of shelf appeal was a big factor here as well... #Enjoy!
