Discussions about starting stacks are completely irrelevant and detract from the main focus - which should be the blind level structure, pure and simple. 15k, 20k, 30k - doesn"t matter if the levels aren"t correct.
PLO events may need slightly more chips or more/slower levels due to higher average pot sizes.
And lammers for the heads up (and maybe the PLO events) for a few levels to even out some variance.
