I don't think they've been hidden, I think they've had a hard time coming up with something better then the i210 they have out right now. Curious to see if these actually are announced early 2022 or get pushed out further.
I'm a gigantic Ping homer and for the first time in a long time I've put a different brand in my bag. Went from a G410 LST to a G425 LST and now game the Titleist TSI3. I honestly think I'd have to rank these drivers Tsi3, 410, then the 425. Felt the distance fell of substantially from the 410 to the 425. Tsi3 is longest I've played and just as forgiving as Ping.
That being said, game the i210's and will not replace these until the next gen come out. Once they're out, I'll give them some time on the market and test them before transitioning to them.
