I've been reading a pile of mic threads here over the past weeks, trying to grok what makes a "good" bass amp mic. I'm sure a lot of it is musical context and personal taste, but other than that, are there certain characteristcs? Help me out here ...
It looks like dynamic mics are preferred over condenser ... is that because it's not always guaranteed you'll have phantom power?
I suppose a mic that handles a high spl is preferred. Any guidance here for loud rock?
My own thinking says that a really compact mic would be better just to save space on a tight stage, but then, I'm a clumsy ox. If I could hang a flat mic (rather than a stick-style mic ... "side-address"?) from the top of the cab, that would save me a lot of embarrassment when I trip over a mic stand

What kind of options do I have to attach a mic to the cab?
I'm looking at frequency response curves for some of the recommended mics here, and I'm a bit confused. Jimmy made three recommendations that seem to be pretty widely accepted: Heil PR40, EV RE20, and Sennheiser 421. Here they are ...
Heil PR40
EV RE20
Sennheiser 421
All three have a fair amount of low frequency rolloff. Is that desirable to avoid boominess? Is it something you compensate for with FOH EQ? Or is it just a non-issue for some reason? Wouldn't a flatter low end response be better?
My sound has a good amount of mid and high freq content, so I'd want something with a pretty flat response ... I don't think a kick drum mic would appeal to me, but I can see why someone playing dub or reggae might like it. Because I'm not sure if I need to make an investment, I'm looking at lower cost alternatives. (Fine, I'm a cheapskate

) I'm thinking about the AKG P2. It's a hundred bucks new, compact, and has a really flat frequency curve.
Any opinions on this?
Thanks, TB!
