Update: I've order an MX99 184 and cant wait for them to arrive! Decided to sell my near mint condition MX98 184 and FX95HP. May post in buy and sell if someone locally (Vancouver BC) doesnt grab them.
Got 10 days in on my FX106HP last season and pleased to see the thumbnail reviewers as stoked as I am with them. They are the most impressive FX/BMX ski Kastle has built
In terms of just the Kastles, I agree with this. I'd own the Kastle 106 HP and the MX 74, as a two ski quiver.
But I haven't skied the MX 99, and am told it is fantastic, a different ski I'd like. Not sure, but....
When I stopped by a Kastle dealer, I was told that their favorite Kastle is the MX 99, a wonderfully better ski, they said.
My question for @Alexzn is, can you feel an effect from the carbon other than it dampens? Does it effect the liveliness, rebound or the way the ski planes in powder/crud/rough snow?
