News to me. If the clubs are getting damaged, I would think it is from banging against one another. Either from carrying or on a cart. Which type of bags were they being carried in? I have a set of the original AP2s (2008) blades and they are in good shape for their age. They were carried in bag, also lugged around on a pull cart as well as on a riding cart.

I thought this referred to the 2019 version relative to the plastic dampener inside of the cavity. And only the irons (4-5-6?) (7-8-9-P?) that use the dampener. I also thought it was improved with the 2021 release.

In any event, I have no opinion on your question on the bag and for myself would not adjust the bag for the irons. Your best option might head covers for the irons.

I’m of the opinion that the more compact the irons to one another, the less bag chatter there will be. I carry or push cart 75% of the time and have no issues. I have both a Hybrid 5 and Players 4 for reference.

In a 14-way, the way most dividers are designed, club heads generally have the ability to rotate something like 270°; thus causing each club head to nudge against its neighbour.
