Finish CDX First?

I am wondering if I should just trial in obedience until we get our CDX. As you know, we have no legs yet. I have 4 attempts coming in through mid-April. I only have so much time on weekends to trial per month so I am thinking, hard as it is, that I may put off trialing in NADAC agility until we get our CDX. There is a NADAC trial close by in early May but also an obedience trial that weekend. I can usually enter NADAC trials late, even day of show, so I could go to NADAC if we get our CDX by then.
