I took the approach of having my PSO recommend some pin up, pin down, x-hole, no x-hole layouts. Then once I have found some that my eye likes seeing going down the lane, I stick with those. Something I like for asym solids, asym pearls, sym solids, and sym pearls.
Usually about anything between 4-5' pin and 30-50 degree VAL angles will do the trick on about any of them.
