Doubt about M2frame standard lens comparing with MFrame Sweep lenses.

[mendiz]

Hello, I have 5 M frame Sweeps, I love this shape for Road cycling, I had Heater and the airflow was bad climbing a long climb in summer. I am going to buy M2 frame , I tried in store with the XL lenses , but trying the standard lenses is impossible( only custom in Oakley.com? I have added a pic where Revant compare the size of standard and XL with Sweep. I read some time ago here I think that Oakley released XL version because Standard lenses was a disaster letting too much air in the eyes. Anyone M frame Sweep and M2Frame standard to compare?
