I use 155k as well. SET taxi out on the NG is almost impossible to do even at that weight with the 40% restriction.

The only time I really notice the fumes from #2 is with the tailwind.
Crosswind/headwind, I can be on the APU bleed with #2 running with no issue most of the time in terms of breathing engine exhaust.
40% restriction no longer exists in the AOM. It just now cautions us not to use excessive thrust in congested areas and look at the 7 pages if SET in the ramp isn't allowed.
