Dominant 7 Chords

I was watching some You Tube videos this afternoon and came across a nice lesson on the mixolydian/blues hybrid scale. You know, for all this time I've been playing guitar I never thought to put these two scales together. Its a perfect match, hell I probably already do something like it already when I solo, but now I can dig into it... when I get my wrist back in working order. All this time away from practicing allows me to find stuff like this though, it really is beneficial for my growing-as-a-musician. So anyway, after I found this I tallied the amount of scales available over a plain Dominant 7 chord, the ones I thought of at least.

• Mixolydian (1-2-3-4-5-6-b7)
• Blues (1-b3-4-b5-6-b7)
• Mixo-Blues (1-2-b3-3-4-b5-5-6-b7)
• SuperLocrian (1-b2-b3-b4-b5-b6-b7)
• H/W Diminished (1-b2-b3-3-b5-5-6-b7)

So I figure that in order to successfully (note: subjective) play over a Dominant 7 chord, just avoid the major 7, anything else is permissible... hahaha.... hell you could even play wholetone (1-2-3-b5-b6-b7)!

I'll keep this in mind when I start up again.

edit: Forgot about Bebop Dominant scale (1-2-3-4-5-6-b7-7!) but the 7 is only a passing tone in either direction...
