I've had CNC short levers on the bike for about 2 weeks, I'm only a weekend rider so have only done about 200 miles so far but as 2 fingers are always on the bars I feel more locked to the bike, especially when hard braking. I know you can use 2 fingers on the long levers but it never quite feels right. I'm guessing that there's also maybe less tendency to lock up the front as you're only grabbing the brake with 2 fingers rather than 4. For heavy clutchwork when filtering through traffic I also seem to be more in control as more of me is on the bars.
Some like 'em, some don't...seems to be a personal choice I guess but they deffo suit me, best £23 I spent yet.
