I recently purchased a LN low angle block plane. What an incredible tool! I think I'm going to be addicted.

I'm ready to purchase my second hand plane, and I am still a bit bewildered by the selection. I am planning to use my handplanes to face joint boards wider than my 6" Powermatic can joint. What plane would you use first in that process. I guess I am leaning toward the LN #5 or #4 1/2. Am I heading down the wrong road? Any good suggestions for this Neanderthal rookie? What about low angle vs. standard vs. high angle?

Thanks in advance.
