That was very kind of you Wm Stratton! Simply put, the letters represent different set bonuses you can get if you have multiple of that set on those clubs. We have the chart available with more info on our help page here: https://perfectswing.freshdesk.com/en/support/solutions/articles/47001026347-how-do-club-components-work-
We also have a video going over all the club stats.
There’s a chart somewhere that shows the club color differences and the 8 letters for components. I tried to find it for you, but don’t remember where it is. I took a photo when I found it and will attach....
I hope....haha.
