Purchased the Line 90's last March. Fun at Gore last few weeks of season, but not good in the trees (think Barkeater Glades). Also used at Stowe in early April, great in corn, but again got in the trees as they had some fresh snow up top, they would not react quick enough (needed my Blizzard 8.1s)
HOWEVER - used them at Squaw and Alpine Meadows in mid-April, absolutely loved them. No problem with the heavier snow.
Bottom line, stay out of the Eastern trees, and you'll have a blast with the 90s
I demo'd Dynastar's (forget name here) 86mm under foot slight rocker the first week of December last year. (at Gore) Powder was great, hardpack all I had to do was rotate then apply edge and they would pull any radius turn I wanted.
Used the NYSB Daily Breads (rockered tips) the last week at Gore. One thing I learned:
Rocker can come in really handy in tight stuff. Many trees were in play but those with less traffic, especially off the map were punky outside of the primary line. A bunch of us went into BBA and I chose the far left line as I thought it would have had the most traffic. If you know that line the end is extremely technical (hard). It takes four super precise bang-bang turns, or a deliberate on turn at a time approach.
You're in awkward icy troughs that are so small that your camber does seem to be a hindrance. Not describing this very well, but the rocker really seemed to help me get through.
Maybe someone else who knows the spot can do a better job of describing it to those who don't ski Gore.
