Witbier

I made the yeast starter today. I'm thinking my bill will look something like this:
6.0 pounds malted barley
4.5 pounds malted wheat
1.5 pounds unmalted flaked wheat
1 pound umalted oats
.5 ounces coriander
1 ounce bitter orange peel
1 ounce of my secret hop variety (will be high in the ibu catagory).
I should be able to start on my usual Sunday. I'm calculating I'll achieve maximum SG of 1.076, but estimating I'll only get about 1.060.
