Male Pollen X S1 of the same strain?

[Osric]

Let's say I grew a crop of regular seeds and culled the males except for one tucked away somewhere safe with pollen stored. And in the empty pots I planted feminized seeds made from plants in the same generation as the regular seeds. If any of them looked particularly good would pollenating them with that years stud be worth while as a way to preserve anything special about that plant? Can I expect anything different than pollenating regular plants?
