Replying to Shift vs Duke pt

Would be going on rmu yle pro

the shift will fit better 120 brake vs 125

so will I notice a brake 7mm greater than my ski? This is my pow ski btw and all my other skis have brakes that are less than the waist width.

Also any other reason to go duke vs shift? I can get the shifts for $350 rn almost half the dukes cost... 😐
