The mool mantar debate has been ended once and for all by an intelligent gursikh:
Nowadays we have idiots who say in their katha that those who read upto gurprasad will go to hell. But they forget their own taksaal says upto gurprasad is a valid mantar - maha mantar. If someone calls it mool mantar then let them, no harm done, from your point of view you can just think they are actually doing maha mantar which is perfectly valid and acceptable as a mantar in taksaal.
So I hope this is one disagreement in the panth which can be left alone.
Everyone agree?
