The Straightback could be a Turbine rotor with different temples. they fit well and have good coverage. the price point makes them a little more affordable to get the prize lenses. also. The Scenic Blue is the only real frame color spinoff with the blue glitter frame which is really cool in the sunlight. My choice for these was because I'm a nut for shield lenses and the 24k more specifically. You honestly won't be dissapointed in a purchase, they fit well and don't pressure the head too much. The rating is based on my opinion Lux is just throwing ideas at the wall to see what sticks.
