Thank you guys for the quick and honest responses, I appreciate.
LNIDA:
I'm honestly not looking too far ahead, definitely not at the end of the runway.
I used to ask my instructors often, and almost all of them don't look too far down the runway. I will try to look a little further down and see how goes.
Some of my instructors would advice to break the ROD at 50 feet to about 400/500 FPM when on a 321 especially if it were on the heavy side..
Again thanks guys.
