Can I look up and see the crossbars? Yes.
Can I see 2.5 or 3.5? Who knows? I look up at minima. I can see two cross bars - maybe the outline of a third. I'm back down on the ADI before I can count the exact number of lights at minimum RVR.
I use the F/D or ILS from 200' to 100'ish then I'm heads up. For CAT II or III - it's as discussed.
If you can fly an ILS to CAT 1 and at 200', manually flown, be head up long enough to count the cross bars plus other lights well done, you're a better pilot than me.
