Aerotech SteelFiber Hybrid (HLS) Shaft (0.370" tip)

Stability/low torque

I have aerotech shafts in all my irons, hybrids, fairway woods and driver. Not in my sand wedge or lob wedge. They are lighter than steel and very stable.low torque. Predictable in all shots.

not as good as a KBS Steel Hybrid but still very good

I am playing Titleist 818 25° Hybrid and 21° Hybrid, the 25° is with a KBS steel hybrid shaft the best option I figrured out in several tryouts... For the 21° I was never satisfied with the stock Tensei blue, but all other options seemd to be not a step forward. But this Steelfiber HLS is a significant step forward
