Question
What numbers do you recommend for the beginning of spring?  Is 16-16-16
better than 29-1-4?

Answer
Not necessarily. If those are the only options you are offering, I'd do the 29-1-4 at about 3 1/2 lbs of fertilizer per 1,000 square feet. You don't need equal amounts of the second two nutrients (Potassium and Phosphorus) as Nitrogen (the first number).

In the end though, it's more a function of how much you put down, and how well you apply it.
