I've had a pair of Scalpel's with OO BIP (thanks @wilkie18 ) for a while and of all my lenses, those are the ones I enjoy looking through the most. I just got some Flak Jackets with G30, and they were awesome on my commute today when it was overcast. I'm pretty sure the G30 is the base lens for OO BIP isn't it? What other lenses have a rose base? G20? G40? Others? Thanks.
