Svend...duely noted about the twitchyness....the problem I assumed would occur with a pow ski. Glad to hear you got that worked out. Truly do like the crud busting, solid feel at speed performance of the MX78....It's going to be a difficult ski to replace one of these years.

I think so.  I haven't skied a Kastle, but from the reviews of the MX78, it seems to be up there with the best of the 68 to 72mm high performance skis from such marques as Stockli, Blizzard, Fischer, Head, etc....  It would have to be an exceptional ski to get you to change. 

And I think the added stand height will effectively erase whatever overlap there was with your FX84's, and will make the 78's much more agile, responsive and quick, making them more "narrow carver" in character than with the flat mounted Griffins.  A good move, and something that will rekindle the fire you have for those babies.

Looking forward to more reports....

Re. the Powerail, from all the positive reports on these, I will likely be mounting them on a new ski I bought for Terryl -- the women's version of the iM78.  Should be a perfect match.
