JodanorNoDan is correct on only getting morpha out of supers, it's a great idea.

HOWEVER, I highly suggest multiple morphs, even then. It gives you more possibilities, and while you still have that normal possibility, it gradually becomes statistically insignificant the more morphs you have in the mix. The rewards become potentially greater, but the fun is much higher (in my mind). Plus the more morphs in your collection gives you a stronger starting point for breeding
