Titleist Iron Set - 710 cb

I have a set of Titleist 710 CBs 5-PW. They are 1 inch long and 2 degrees upright. These have Project X 6.0 shafts in them. I have had them for 6 seasons and used them three times a week over that time. I bought these while playing college golf and have always taken pride in keeping my clubs clean and in good shape. The 6 and 7 iron have some marks from playing out of waste areas on the bottom (shown in pictures). They're in very good shape for being a few years old. The grips are new. These have a lot of good golf left in them. Sadly I don't play as frequently and found that I needed to try some irons that are a better fit for the current state of my game.
