I recently went through a Titleist fitting for the new T-Series irons and utilities. I hit every iron, the T100, T150, T200, and T350 as well as the U505 and T200 utilities. And I can sum up the entire fitting by telling you this T-Series is Titleist's GOAT. No exaggeration.
Something was legitimately improved in every model. In some ways even significantly improved. And more than any line in Titleist history all four iron models blend about as perfectly as possible for combo variations. I'll let you know what my ultimate set wound up being at the end.
