i'm looking for everyone's choice between these two RACI finders. i will use my Rigel, but also want one of these for my 6" f5 refractor. i am leaning to the 6x30, even though it's the smaller of the two, it has a nice 7 degreee fov.
the 9x50 would have a 5.5 degree fov, but more light.

so even though i am leaning to the 6x30, i am looking for everyone elses thoughts... which one and why?

thanks,
david
