Just make sure your extract to grains are about a 50/50 mix.
Another thing I do is use LME for 3.3lbs or whatever container size I have and then use DME for the rest. Save money with LME but try to use DME as much as you can for various reasons (color, taste, anti twang).

Bottled! Award winning East India Porter, Oatmeal Stout, Milk Stout, Saison fermenting at a nice controlled 85 degrees (up from 70) as it should be - weird isn't it.
