Just because a ski like these costs less does not mean it is a downgrade.
For example, to me both the Kendo 88 and the older versions of the Brahma 88 are much more comparable skis to the Monteros and Lasers I've tried or owned, not cheaper downgrades. There are pluses and minuses to each of these skis, on an equal or near equal footing.
And the preferences are partly subjective, including those surrounding such huge cost differences.
Nonetheless, they tell me that the new Montero AR is improved from the previous Laser AR models - more versatile maybe?
Less confined or glued to its own particular carve perhaps?
Also, the newer Kendo 88 is much improved, really a standout, but still with pluses and minuses.
(And to me, the newer Brahma, in particular the 88, is less dialed in than the previous version of a few years ago - don't know about the 82s.)
A buddy of mine in the business, whose ski choices I learn from, loved the Kendo 88s and owns last year's, downsized (170) version
for bumps and trees, and steeps.
He has just gotten this year a pair of current Montero ARs in 180.
That has put that ski, at that length, back on my radar.
(I could easily have owned the Kendo 88 ski, which is really good; but I own instead a downsized pair of the earlier version of the Brahma 88/173s.)
(For what it's worth, a carving front side biased ski this narrow (like the AR) in 175 or so is often likely to be too quick from edge to edge, in an "in between" sort of way that is to me a bit awkward, unlike the same ski in 168 or less - or in 180 or more.)
