That was also one of my gripes. I put the large pro ICU in the Ajna and it was very difficult to get lenses in and out near the edges of the bag.

The larger ICUs can cause some problems with all these packs.FWIW, the f-stop ICUs and [of course] the Shimoda ones fit well in the Shimoda 40L. It's opening is book style, and I have found it slightly easier [though not without some pressure] to get things in and out at the edges. Of course, it all depends on the size of the ICUs, the stiffness of the ICU, etc. I have also found that the padded foam inserts of Pelican 1535 Air cases fit very well inside a Shimoda 40L, and the padded foam is less stiff [though potentially less protective]. This is my primary travel rig. Last pic shows the Peak Designs 20L which is my true carry-on backpack. If folks at the gate refuse to let me carry the Pelican onboard, I move the batteries, laptop, Phase DB, and Hasselblad to the backpack, and check the Pelican. Gate checking is often, though not always, a gentler process than luggage checking at the front counters. The Shimoda shell flattens well and travels inside my checked baggage.
