No longer middle-aged eyes, full on OAS eyes for me. I've switched over to Austrian or German optics with "tree-trunk thick" German #1 or #4 reticles. As long as your optics are not ca-ca, that's all you need for almost too dark to shoot light.
The problem with a massive objective lens is that you will likely not be able to get a good, repeatable cheek weld, which is necessary for accuracy.
See if one of your buddies has a Swarovski, Kahles, Zeiss, Schmidt Bender or Hensoldt scope with that reticle that you can look through, especially at last light.
Even if it of lesser power, the good glass & the reticle, will prove its worth.
