On the Ken Farrell site the 0 moa flatback rail is offered in a low profile. Can anyone offer an opinion on standard vs. low profile?

Seems to me the standard may work best with a blind mag. Which is my setup.

How would it compare to the egw I use now which leaves plenty of space to load but raises optics considerably. Really too high but lower rings can compansate for this.

Would the Burris tactical 2pc extended be a better choice with the blind magwell? I don't see it giving much more space, but a slight gain.
