Hi, I have also been diagnosed with the long oval. I bought an Ls2 Strobe (if you have been to Revzilla you will know what I mean) Even in a 3xl it was too tight even though the skull measurement should have been way too big. I have not been able to find a decent fit for me, so I have made a crusade of it. One of the guys posted that anything above xl is the wild west size wise and all bets are off! I remembered back to an HJC ff that I had tried and it felt great. However I wanted a modular so I bought a xxxl Hjc cl max 2 ridge. This helmet fits very close to perfect for my needs and it is not the long oval shape. I think it is a slightly round oval. I feel the actual helmet liner is the perfect size but the cheek pads are too thick. I have a new set of pads on the way and I suspect my helmet troubles will be over. I am beginning to think that you cannot get a decent fitting helmet without changing the liner and cheek pads to fit you. However these manufacturers are going to have to make it a lot more accessible to get actual pad thicknesses. You will ultimately have to determine your own head shape, Do not rely on what the sales associates tell you.
