My new +4" CeeBailey is in the brown truck and scheduled to be here on Tuesday morning.
Matt,
I would suggest the +2 , +4, then leaving it a couple notches down. I have a +2 "flip" and normally ride with it in position 3, the center position. When I want more airflow I just "slap" it down to the bottom position and I get all the air I could want... BTW the "stock" replacement Cee Bailey, in standard size, doesn't have the "flip" so you are not gaining much IMHO...
Maybe I'm experiencing optical distortion, but photo 4 looks darker to me.
Thread Hijack alert!
LOL, I guess I am too as that looks a lot darker than my light grey... Here are a couple of photos of my light grey +2 "flip"....
