It's great, it absolutely improves response. anyone can go pull their brake lever and literally watch the cable housing flex. It's not gonna break the cable, it might pull cable outta knarps if you're not tight enough. One thing though, do NOT use derailleur linear cable housing. only use shit made for brake cables. and obviously need the right ferrules on the ends or the reinforcement wires all just splay out and it's useless.
But yeah, the derailleur stuff (even w proper ferrules) will split if you put alotta force on it. the stuff made for brakes is much stronger reinforced. the cable housing if you use the derailleur stuff can just split open... like picture if you tried to bend a banana in half. It's also kinda more of a pain to work with, you need legit cutters and it doesn't wanna bend as sharp to snake around behind the headlight whatever, but that isn't really a big deal unless you got dumb loops.
the levers comment is totally fair too, plastic levers bend more than the cable housing so that's def a 1st piece to replace, and the cantilevered and longer ones are obviously gonna give you more pull in shorter range. Bike levers usually are shorter than moped which are shorter than motorcycle, and the length is duh proportional to how much lever you've got on there and the cable diameters scale accordingly too. heavier bike longer brake levers bigger brakes thicker cable. I suppose you could got the other way, go full moto and hulking overkill instead of getting smaller high performance bicycle stuff
sometimes the more gradual pull is preferred though, as long as you've got fully taught at the end, it's just a matter of responsiveness.
