I don't like the flow because the hard k sound in the first name leads into the MN. So it kind of sounds like one word, "draycruz." But this would probably be more of a problem if Cruz was your last name rather than the MN, so it doesn't really bother me that much.
Re: Does this flow...
Well, it doesn't flow the best, but I think the familiy significance outweighs the choppiness.
I think you're good.
I agree...if it's important to you and you like the name that's what really matters.
That's a rule? Seriously, who comes up with this stuff? I think it sounds just fine.
I guess I'm a big ol' rule breaker!
