Aww come on and try using FL180 as the transitiion altitude. You will come to love it <G>... We use it with no problems at all here in both the low lands and some of the higher ones...
As to the higher peaks in some areas, that isn't an issue either. Your minimum IFR altitude is known and you just can't use an altitude that will be in the rocks... NO PROBLEMS...
