Most golfers spend more time tinkering with the top of the bag than any other section: debating long irons versus hybrids, wondering where to make the switch, mixing in a utility iron to fix a height problem. I just went through it, adding a Titleist T350 5-iron to improve launch while keeping the T250 for the rest of the set.

A recent Titleist tour truck video with Cam Young showed exactly why these decisions matter: tour fitters don’t build long-iron setups around distance. They build them around ball-speed windows and trajectory control.

Tour fitters blend models to create the right ball-speed window

In the video, Cam Young’s irons transition from:

631.CY in the 6–9 irons T100 in the 5-iron T200 in the 4-iron

This flow isn’t about adding distance. It’s about ensuring the larger, more forgiving heads create the extra ball speed needed for proper launch and descent angle in the long-iron window.

Tour fitters typically look for roughly 5–6 mph of added ball speed when they move a player into a bigger chassis. That speed bump creates:

A higher launch More peak height A steeper descent angle Better ability to hold greens from long range

The T100 and T200 aren’t “distance irons” in Cam’s bag, they’re trajectory tools.

Why ball speed matters more than distance

Two long irons can go the same distance but perform completely differently.

Too little ball speed → low launch and flat landings Too much ball speed → shallow descent angle and no stopping power Wrong head size → wrong height and spin window

That’s why even one of the fastest players on Tour carries a 21-degree hybrid. It gives him the ball speed, launch and descent angle a long iron can’t always produce.

How amateurs can use this

You don’t need tour-level speed to benefit from the same approach.

When you’re deciding which long irons, utilities or hybrids to carry:

Look for 4–6 mph of ball-speed separation when moving into a more forgiving head. If your long irons fly low and run forever, you may need a larger clubhead and more speed. If your short irons fly too high, a more compact head can help you control speed and spin. Don’t force yourself to play a 4-iron if a hybrid or hollow-body model launches and lands better.

Final thoughts

Tour fitters don’t build the long-iron end of the bag around distance. They build it around ball speed, height and descent angle. If you want long irons that perform instead of punish, start paying attention to the speed windows your clubs create. It’s one of the easiest ways to make your bag work smarter without changing a thing about your swing.
