Bob,

I have felt for the longest time having experience at an elevation is more important than short term acclimatization.

This is why I am big on noobs going to White Mountain or Mt. Langley, once snow clears of the New Army Pass, prior to coming to Mt. Whitney.

I do not have problems going to 14,000' after not being at the elevation for a couple of years because I know what to expect and how to adjust my pace, etc.
