I'm hoping someone from Titleist can comment. I know in one of the fitting guides you state that for drivers, a decrease in loft by 1* reduces launch by approximately 0.75* and spin by around 300rpms. I'm curious if there in similar information regarding the relationship between iron loft and launch/spin?

I am a 5 handicap who launches my irons too high and with too much spin. My 7 iron ball speed is 110mph, launch is around 21* and spin over 7000rpm. My landing angle is regularly over 50*. I use 714 Ap2s that are 1* strong.

I am wanting to get launch down to around 18* and spin to just under 7000. I am debating between the T100s and T200. I am thinking the T100s that are an additional 1* strong might be the best solution.

I plan to go through a fitting but recognize that my swing isn't always consistent so I like to arm myself with info before I get to my fitting.
