i feal like a dick for doing this but what year are your karma's and what size? cause i would def. be willing to buy them if you need money for new skis.
the walls are terrible in powder center mounted but a decent park ski. i dont really know much about the bridges but ive heard that they are a good all mountain ski. id personally go with the msps. theyre sick backcountry and on the groomers, a fun park ski too.
i have 177 walls im 5'7" ish and they are too stiff for me and they suck at powder if centered, and if you get them its dumb not to center them cause they are true symetrical twins
If you like stiff pick up the msps. Damn stiff ski that will ski anything and everything and still reasonably light. You can lap through the park a bit, carve hard on groomers, and they're alright in the pow. I love em as a tree ski.
