Interesting trick on the lever’s lateral position, TrialsRider. I normally use two fingers to clutch/brake and I was thinking it was too bad that I couldn’t take full advantage of the leverage offered by the long levers since my index/middle fingers are closer to the lever pivot points. I could move my hands outward more (toward the bar-end weights) and achieve the same effect you’re showing (pulling on the levers farther out from the pivot), but that would result in longer reach for the levers, which makes lever control a bit harder, so it seems a wash. An adjustable-reach clutch lever would be nice.
Back to the angle thing. The clutch lever on one of my bikes is noticeably stiffer than my other bikes. When I first got the bike, I had to bend my left wrist up slightly, and I needed to use 4 fingers to control the clutch lever comfortably at low speed. After I angled down the clutch lever, now I can easily use 2 fingers again.
