^^^ I see it the opposite way. Skis in the 97/98mm range are wide enough to start to feel wide, yet they don't really float very well. I like these skis for the 'any condition/ any day' ski, but they are a serious compromise on both hard and soft snow... jack of all trades, master of none, Around 105 underfoot still feels clunky on hard snow but there is a noticeable improvement in soft snow performance.
I agree, I haven't liked the 98mm skis I've demoed. Seems like they are much more sluggish than a 88, yet don't float like a 108. I go 88/108, but am thinking of replacing my stiff 108's (cochises) with a more playful 108-115 ski.
