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.
I think the 98s are more versatile and maybe even better in pow than the 100s, unless they added rocker to them. I had the regular 100's a few years ago and never really got them.
As far as a quiver goes, I skied 75 percent of my season on the Worth Humpbacks (106mm) after selling my Praxis Mountain Jibs (116mm).
