As a LH golfer, when the current generation came out, oil can was not in the release. Even Titleist fitters couldn’t get the T250* fitting head. So I ended up with the T350.
I had a GT-1 driver that would balloon far too frequently. Had to try the GTS-2, and it worked. With some extra time, the LH T250* was available. It was a delight to hit, but with the loft between the 8 and 9 T350, the launch, spin, and distance was also between those 2 clubs.

As the rest of my bag has been adjusted for gaps with the T350, the aesthetics weren’t enough for me to spend another grand and possibly change wedges and metal woods to re-gap. I likely would have taken the T250+ if it had been an option with the new release..

If you can still hit a standard loft 5 iron, the T350 maybe a better choice. The loft on the T250* 5 iron is closer to my 7 iron in loft.
