Experienced and reasoned response. For those not familiar with the OLAES: https://www.youtube.com/watch?v=joKzsp4_ow0
The thing I like most about the OLAES is its additional length of gauze without needing a second package for it. I find packaging quirks in any dressing tend to be more about shape than overall size, and depend on compatibility with the intended pouch and preferred packing arrangement. In some, I can carry an OLAES and a package of QC in the same space other dressings and a QC take up, leaving me with extra gauze. I also like the OLAES for issue, as its simpler for troop to manage and be accountable for only one package instead of two. I can take or leave the sheet of plastic intended for occlusive, as the packaging serves the same purpose. I have yet to use the pressure cup for eye application, but know of credible accounts of same.
I share the opinion the OLAES elastic is not as robust as the ETD or IBD. In training kits, I get fewer reps out of the OLAES. In patient use, I've found it quite adequate. Complex junctional dressings of any manufacturer often benefit from an additional roll of ACE/control wrap.
An additional option for true minimalist carry is the SWAT-T, theraband, or esmark with a package of hemo or regular gauze.
