>>1978903>going to hinder performanceThe thicker the pad, the more squish it has when it's being pressed against the rim. Some of your effort at the lever is always being used to deform the pad, but it's a greater amount w/ 'tall' vs 'short' pads.
Maybe there's some situation where you want that squish. But for me, on an old touring bike w/ cantis I swapped from the tall/thick pads to a thinner Koolstop one. It greatly improved the braking feel.
>cause it to contact the rim at a weird angleWith some canti types where you would have to swap out the standoff/spacer when changing pad thickness.
But a pretty typical road shoe (pic), you just tighten the cable a bit, and use the spherical washer to get the angle/rim contact you want. Though there are some cheapshit shoes/pads that don't have any kind of adjustment--just don't buy them.
