A nose heavy plane won't fly well; but a tail heavy plane won't fly at all.
I thought the saying was:
A nose heavy plane flies poorly, a tail heavy plane flies once.
Fly the plane with the CG where it is. If it seems poorly responsive to the elevator, or won't slow down to land, do whatever it takes to move the CG back a bit. You are close enough that it should not be a huge problem.
