The edge hold of those more front side oriented skis was fantastic on the refrozen spring bumps, though.
I'd love to hear if anybody has suggestions for a replacement
By front side, I suppose you mean the 8.5 Ti? Those happen to be my favorite skis as well. I discovered them as a rental ski at Tahoe, and they were superb in 7" powder at Heavenly and Kirkwood. And, before it snowed, they were also amazing on bullet proof ice. Plus, I love the bigger radius, 19.5, on my 174's, same as yours! So, when I got home, I bought a pair. At 174, they can maneuver playfully in tighter moguls and trees. Big turns on hardpack or ice, no problem. But, yes, had to start thinking of a replacement. My choice, the Brahma's, last year's version, but this year's has excellent reviews.
End of last season, I demo'd them on a frozen over alpine and sub-alpine at Blackcomb. Amazing. So sweet that I could still be playful on rock solid bumps, as well as arc nice medium turns, I don't know what it's called, on frozen over fields of tracked up snow, so solid, no spray, except maybe chunks of ice. Though I didn't have a chance to ski them in powder or soft packed powder, I could feel they would be great, as they are reputed to be. I got the 180's. But they ski short, as they have more rocker than the 8.5 Ti's.
I demo'd the Bonfides at Blackcomb too. Also amazing on ice, but big turns. Bought them too. I've also skied them in Spring conditions, the Eastern melting ice kind. Slushy on top, kinda hard below. If you want to fly from big arc to big arc, like a monkey swinging from branch to branch, through wet heavy slush, even bumped, these are it.
Of the two, which is the better replacement of the 8.5 Ti? The Brahma. Demo it. And, I think last year's model will come the closest. 180, that skis shorter, and 19 radius. This year's, less rocker, so probably skis longer, but has shorter radius, 17, so probably evens out.
