Louise, The Blacklight 88 is lighter, slightly stiffer, and has a little bit more sidecut. The Radical 88 is slightly heavier with a damper core and slightly less sidecut. The Radical 88 is not quite as turny but easier to ski overall. It also holds its course a little better in chopped up snow as well. Both would used for similar terrain but the Radical 88 would pair with a beefier set up a bit better.

Caleb-We have not tried running with this pack. It fits pretty close to the back so it might work ok. You could look at this pack if you need a larger size pack for running.

Karl- The sizing on the Raceborg is different to the Skorpious. Skorpious uses traditional shell breaks as in 27.0-27.5 is the same shell and 28.0-28.5 is the size up. Where the Raceborg uses a different break point of 26.5-27.0 are the same shell and 27.5-28.0 are one size up. Fit is different enough which might be easier to discuss reaching out to help@skimo.co. You can punch the lower shell no problem as it is straight grilamid.

Martin- The M-vertical definitely requires a bit of better skier. Both have very good edge hold on firm snow though. The slightly friendlier ski would be the K2.

Barbora- The M-vertical is very different to the Mtour 90 in shaping and rocker profiles. The K2 would be more similar ski, both have great edge grip with the K2 being just a bit more forgiving.
