CHAS,..great choice,..
I don't think D/T floods the market,..but each and every new ball (usually every 6-8 weeks) gets better and better...
I used the HE at Nationals last year,..it was just off the press,..won about 8 grand,..STILL tickin'...
One thing about our equipment is that there always seems to be a little more innovation in each ball that keeps them very contemporary...although I'll be the first to admitt, that I never leave home without my THING, Ven BLACK, or AU79,..all which have 100's of games on them...jim
