TT Lite XL Iron Taper Shaft

The shafts start at 40 inches and go down to 36 inches. I

Situation 1

The 40 inch is for a 1 iron (36 inch is used for both the 9 iron and PW).

Situation 2

The 40 inch is for a 2 iron (and the 36 inch is used only for the PW).

Which situation is correct?

I agree with situation # 2

The difference between P-wedge and 9 iron of most of iron set are :

1. The swing weight of p-wedge should be bigger than 9 iron at lease 1 swing weight.

2. The lenght of p-wedge is 1/4" shorter.

3. The flex of p-wedge should be harder than 9 iron.

If the shaft have same flex, the p-wedge may be slightly softer than 9-iron because of the bigger number of swing weight.
