I've posted some of this in other threads about the axys 13.5 degree straight angle.
The problem I see as polaris changed to this straight angle is on the "S" models mostly.Belt heat,slippage and rpm loss/drop.
The sheave face angle of the 13.5 degree straight up-shifts quicker then the multi-angle polaris has used in the past. It's not as trail friendly with most of today's riders as the multi-angle in my opinion. Add the quicker up-shift,light primary fly weights,belt compounds,and the 1.61 ratio combining with all this in the "S" package. It has a tendency to be more inconsistent with all these combinations. Meaning hi-heat in primary,belt slippage,constant belt residue,and primary heat 20+ degrees over secondary usually.Add the 1.61 tall gear ratio to this like I've said,and it can be inconsistent. All this can cause rpm loss/drop.
A solution to this can be switching the primary sheave face angle back to the multi-angle,having different belt compounds, and installing a gear ratio in the 1.7's on all S models.Adding 4 grams more weight to help pinch belt better creating less heat and a more consistent set up.This is just my opinion and the way I see it.
The straight angle is better for drag racing.
The mutli-angle is better for the everyday average trail rider.
Since there is a low % of people who mess with clutching to drag race and just want to turn the key and ride. I would choose a more trail friendly version as I've mentioned.
