Jacob, I can't imagine you would notice much difference between your and full length connectors. I went full length because they offer some added stiffening, becuase all connectors (short or long) are cheap compared to the improvement, and because I didn't want to ever think (like you) man I should have got the long ones. I mean, who would want to rip off short connectors for long ones, that's nuts.
But anyway, I would guess there is a marginal difference. Certainly nothing like the difference between stock and your set up now.
