I have found the solution! At least for me:

These are the Shure soft flex sleeves for the Shure e2c. If you are not familiar with that phone, it is no longer made but what is important is that it was a larger diameter nozzle, similar to the Panasonic HJE900 or UE TF10. This means it has the larger sound hole. It is also a different (better/softer) material than the Shure soft flex sleeves with the small sound hole that fit the Atrios.
To make them fit, I cut the stalk off a pair of the stock FS biflange sleeves. I put the cut off stalks on the Atrios and then slid the PA749M (now called EASFX2-10M) on top of those. These are extremely comfortable and best of all have the same bass as the foam olives but also have the treble of the stock biflanges.
This also would work with the Sony Hybrids. The problem with the Sony's is their medium is smaller than everyone elses definition of medium, so they are too small for me. Once again these Shures work perfectly! I had already owned these Shure tips b/c I used to own the e2c and had forgotten about them. Finally my Atrio sparkle is back!!
Edit: To me these Shure sleeves are more comfortable/softer than the Sony Hybrids.
Edit 2: Some of the pictures sellers use for these make them look like the version with the smaller hole. I assure you they are not. The smaller hole sleeves are grey and are for the newer line of Shures. The larger hole version is black and is for discontinued models.
