Replying to Smith I/o vs I/os

Hey gals ...
Was wondering if anyone has had any experience with i/o vs I/os goggles ..obviously the i/os are made for women and the I/o can be more unisex but if anyone has had and thoughts on buying one over another with a female face. I've tried on both and an leaning toward i/o but thought I'd leave this here before i spend and arm and a leg on these.
Only justifying this purchase because I got my hands on a new variance helmet for $40 (retail $180)

güîćčì thanks
