hafa8pt, I might be mistaken, but I don' t think the spiral cam 1/2 is offered on the sierratec. Besides that, has your wife drawn back a spiral cam? Thats a rough son of a gun! Might be a little to much with a bad rotator cuff. Just something you might want to consider.
My wifes sierratec is on order right now. Camo isn' t that hard to come by, but the flag bow has been on order for over 5 weeks now. But she doesn' t hunt (just shoots tournys). And that' s what she wanted.
Good luck with what you decide.
