Not necessarily. I play it but added more weight in the head and I am using the Tensei Blue shaft, not the ultra light weight option. I have noticed it has a bit more of a "tingy" sound than the other hybrids. Almost sounds like an aluminum baseball bat. I like the performance but not crazy about the sound. Find some place that has some demo clubs you can try.

Not entirely correct. Which model of the TSi line you would play is dependent on your launch conditions, skill level and other parameters. LPGA Player Nelly Korda uses a TSi 1 Driver.

Being LH, my only choices are 23/26 degrees. They would be replacements for 6/7 irons. I have TS-2 21 for a 5 iron and an 18 TSi-2 for my 4 iron. Since they gap nicely with my T300 irons, I don’t feel that TSR LH hybrids are necessary. My driver swing speed is under 90. The shafts are Kuro Kage that are standard in the TS/TSi hybrids.
How you use hybrids and whether the -1 or -2 will best meet your needs is a reason to trial or get fit to your irons.

I have the TSi driver that I replaced the original light weight Fubuki with a Tensai Blue shaft. I was getting launch angles of 15+ degrees with the 10 degree head with RPM over 3000. The Fubuki should have been fine but things happen based on the individual.

I have a TSi 1 3 metal. Like Dale above, I have a heavier shaft (Tensei White) in it and added weight to the bottom. I like the launch it had during my fitting. Ball seemed to jump off the face quicker.

You have to go with what works best for your game.
