When my forged irons are new, I use neoprene iron head covers to protect them from bag rattle if I'm riding a cart, I don't use them when walking using a hand cart. I just sold a set of Titleist AP2s that I kept in iron covers and the guy that bought them said they looked near mint even though they were nearly 5 years old. Sold them for $400.00. So do what you need to do to protect your investment and resale/trade-in value.
