They are in the Titleist Thursday fitting kits now. In store date is mid-November.

Went for a fitting at Club Champion on Oct. 20, 2020. They received their TSi 3 & TSi 2 heads for fitting the day before. According to them, the heads should be available for actual builds on November 1. I will be moving on from my current TS 3 and TS 4 heads to the new TSi 3. I am pairing it with a Motore X F3 shaft. Only had to hit 3 balls with that set up to confirm that I was sold. All three dead straight with perfect numbers for me. Dispersion average was 5.3 feet left.

Mine starts today in Ft. Worth - have a fitting scheduled for 2 PM

How did it go, I have mine on the 29th in Ft Worth.

I did my fitting last Thursday (10/15/20) and they are having one this Thursday where I live at. I know a lot of them filled up quickly but if you go to the fitting tab on the Titleist site and go to Titleist Thursdays you might be able to find a date in or near your area.

As for release date I am thinking I was told early November. (I had to order one couldn't resist it) but don't remember exactly when.

Phil, the TSi is out now for fittings. I just did a Titleist Thursday today and hit them. I didn't believe the hype, but I think they're much more forgiving (even the TSi3) than the current TS series (I hit a 9.5 TS3 now). The pro even tried me in an 8* TSi3 and I was still launching it without a problem. My final specs was TSi2 with a KK 50 stiff (which surprised me). My numbers weren't drastically different than my current setup, but the misses were so much more consistent and almost no loss in yardage.

Titleist is taking pre-orders now and I believe they'll be in the stores mid November.
