Spin is calculated by club speed x spin loft x 2.6 for irons. For the 9 iron above we would expect 81.5 x 34.6 x 2.6 = 7,332 and the 4 iron would be 92.6 x 17.3 x 2.6 = 4,165. A reasonable rule of thumb to calculate spin for an iron is to multiply the iron number by 1,000 e.g. 4 iron 4,000, 5 iron 5,000 etc.
What is the ideal launch angle for a 7 iron? For the driver, a club speed of 94 mph, attack angle of 0 degrees, and optimized carry results in a launch angle of 13.6 degrees. For a 6-iron, a club speed of 80 mph and mid-trajectory results in a launch angle of 16.9 degrees.

The slightly smaller (450cc) head features two interchangeable screws in the front and back, 14g and 2g, to promote changes to launch angle and spin-rate. It has a neutral ball flight bias and the lie angle is slightly flatter compared to the Standard and MAX models. Available in 9º and 10.5º lofts. Features & Benefits 2x10x8 pressure treated.
Titleist.com For every velocity there is a optimum launch angle and spin rate. So lets make up some numbers, lets say 140mph, 14* launch angle, 3000rpm is optimal. If you launch lower than the 14* then the back spin rate needs to go up. With a 10* launch, lower spin is not what you're looking for, you need more spin. For drivers, the launch monitor fitting will correctly determine what driver head type and loft are needed to maximizing your launch conditions (See Below). In irons, wedges, hybrids and fairways, the launch monitor will help us determine which type of head/shaft combination gives you the best launch, spin, descent angle and carry distance ... Attack angle: 0° Dynamic Loft: 10° Spin Loft: 10° Now, you hit down more on the ball: Attack angle: -2° Dynamic Loft: 8° Spin Loft: 10° Because those Spin Loft numbers are the same and you’re using the same club and the same clubhead speed, the spin rate will not increase or not by any significant number.
