The problem with synthetic blend is that they don't tell you how much synthetic is in the mix. If you must go with a blend, then make it yourself (say, 4 quarts of dino and 1.5 quarts of full synthetic, or whatever fits your taste). Just use the same brand and viscosity of oil so there is no conflict in the detergent formulas.

Why limit yourself to those 3 filters? They're all decent enough, but there are lots of good ones to choose from out there. My favorites are purolator and wix (aka. napa gold).
