Last few trips, I've taken my carbon / plasma "TiO2" Juliet with VR28 BIP as a general purpose pair, capable of bright light with a wide range of light condition usability, and aesthetically complimentary with pretty much any outfit. Or lack of... Alternatively, plasma / BIP.
Then as a second pair I took my carbon Juliet with OO Red polar, for more inclement conditions.
These days as a second pair I'd be more likely to bring a radarlock or two with 3 - 5 lens options, mostly prizms.
Vr28bip has always been a personal favourite for myself also especially in a Juliet. I've taken more combos with those than any other and also day to day they're never too far away either. I do find the larger orbital on the XX a real bonus but you do notice the extra weight ever so slightly.Ti02 with vr28 bip........
