So here's what I came up with as a revelation this morning. This was in large part to testing a bunch of the new slim and midfat offerings & then getting tossed on a pair of Brahmas-
( The Brahmas were better than many of them!!!)
Manufacturers are hitting the 75 to 85 mm market hard, yet there are really three factors a skier should be considering when looking at these models:
A) top sheet paraphernalia / external plumbing- One of the features that was highly evident is that ridges, topsheet steps, rods, waves... are one manner of increasing rack appeal. The issue is is that the more you add to the top sheet and the construction, the lesser round and progressive the flex becomes. Heads, Kastles (& K2!!!!) nailed it with smooth top sheets and flex patterns that were not hingy/wonky.
B) reference length- the further you deviate from the reference length the more the manufacturer has to scale the external plumbing/topsheet features to the model. A model that skis very well on the reference length, may be downright binary flexing in a size or two up or down. This leads to lack of snow contact and difficulty maintaining an edge.
C) turn shape variability- if you intend to ski on a size that is not the reference model & you like to vary the turn shape from the prescribed radius, you would be very well served to seek a ski like the flat construction Head Rally, Kastle MX89 or the K2 Speed Charger are all on point here!!!
