After looking at the website my guess is that it's either Tour Brilliance or Fort All Court.
Why?
1 (for TB): Simply, the new Grand Prix can design is purplish (dark blue), similar in color spectrum to the Tour Brilliance. Also the Grand Prix uses the HD core and Max Glo felt, though the TB doesn't give an official name to it's felt in the description.
2 (for FAC): It has the HD core but there is no mention of a high viz felt. Still, when you read the description...
The iconic Dunlop Fort All Court pressurised tennis ball is suitable for all levels of play on all court surfaces and has been enhanced with the introduction of Dunlop HD core technology.
...it sounds to me like a simple rename of their core (no pun intended) offering. In the past that was the Grand Prix here in the US. The key word that stands out to me is "iconic". I take it to mean "staple of our line".
Thanks for helping me
I'm looking for a ball, that feel as heavy and is as durable as the Grand Prix, and also has the extra visibility felt, that the Dunlop Fort Elite ball has.
The Fort Elite is too light and fast a ball - I prefer a more heavy ball.
Tried and at first liked the Slazenger Extra Life, but It's too heavy and feels weird after some time.
So far my favorite is Babolat VS N2, because It's heavy without feeling like a stone, fast without being ligning fast like the Fort Elite and durable. But the Babolat VS N2 lacks the extra good visibility of the Grand Prix and the Slazenger Wimbledon UltraVis.
TW USA won't ship the Grand Prix balls to Europe, so I'm trying to find out if Dunlop has called the Grand Prix something else in Europe......
Still looking and appreciate the help I can get
