Your quiver looks a lot like mine,
A pair of race tigers, Rossi Z9 rock skis, Sultan 85s - my primary powder ski and I added a pair of Surface powder boards this year. I think the first three are all that's needed in the east.
I dig the prophets. Have the 100's. I'd imagine the 98's ski similarly-- though they do have the early rise/early taper for better powder performance than the 100's. Great all around ski. I'm sure you will agree.
Picked up the Bacons last month. I wanted something with a little better powder performance than the 100's without sacrificing too much versatility. So far, I love 'em.
