Hmmm... I'm just thinking Hockey and Golf all use an angle, it just seems to put the head level to the ground which has to offer more control than a head that at 25deg or so. It might also aid release on a hooked head as it's sloped so more likely to slide off. Thinking about my arm position it's at about 45deg from the torso unless the ball is really close in to the bike but even then it's never in line with my body. 90deg is simple but mechanically I think there are better solutions.
I was an early adopter of wacky feather angles on canoe paddles. Traditional paddles were ~80deg feather, for freestyle most people have now moved to 40deg to reduce wrist rotation when surfing waves or doing paddle spins. It's amazing the impact just 5deg had in that sport so I'm keen to put some thought into this one.
