Yasko's Macro thread, changing races

Hi Coach Rich, Finished JOS, A race: IM Canada 8/25, A or B race Pacific Crest Half Iron 6/29; however, I am thinking about changing the half iron from Pacific Crest to Chelan man Half Iron on 7/20.  Your intial feedback was to do HIM week 11 ~16, then switch to IM 09~20.  How would you change that based on these changes?  Thanks!
