A 2 degree adjustment up or flat is doable for any cast head, including putters, with any manufacturer, without compromising the clubhead. The metals used in the casting process today are much softer than the old 17-4 stainless used years ago.

Pretty sure they manufacture the heads at std lie as well as 2 degrees up which then allows them to meet specs from 2 flat to 4 up.

Additionally your wrist to floor measurement shouldn't be used to determine lie angle in a dynamic fitting. Lie angle should be fit via hitting balls. Pretty sure Titleist teaches the sharpie line on the ball as the preferred method followed by lie board and tape.

Good luck with the new clubs.

I'm 6'1 and my 2019 t300s are 2degrees upright. Titleist adjusted mine. 2 degrees wouldn't be a problem. Congrats on the new sticks

So long as Titleist is building your set, they use a +2 head. Even with the stock zero head, bending +2 is within spec.

The lie correction shouldn’t be an empirical decision based on height and wrist height. If this was based on your swing and dispersion pattern, then it is what it is.

Can't speak to whether 2 degrees upright is a good idea for you, but I got my T300s 2 degrees flat with no problems
