Man, the whining on this thread is amazing to me. The staff is making an artistic choice here. I don't know what the program is for the coming year, but perhaps the staff feel that going all-female for this season is a better fit? Is it the best choice? Time will tell. If it isn't, you'll probably see a new staff. That's the risk. No risk = no reward
Will this put PR at a competitive disadvantage? That remains to be seen an well. You have (2) all-male corps that put themselves at a competitive disadvantage in ALL captions year-in and year-out in terms of recruiting, but they seem to survive, and many years even thrive.
SCV and other corps (Bluecoats come to mind - 1990 maybe) have made this switch before. It wasn't that big of a deal back then, but then we weren't "blessed" to have such a "community" where malcontents could whine, dissect and second-guess every decision made in the off-season. We were so deprived back then.
