The low stakes SNGs all seem to have the same blind schdule, in particular I checked the 2.5k to 10k NLHE 9 seated SNGs, but this might apply to others, too. While I personally would prefer a slower structure in general, I particularly dislike the jump from 50/100 to 100/200. This is by far the biggest relative increase from one level to the next. Maybe a 75/150 level could be added?
