I kinda compare straight shaft versus Paralever to driving any number of car setups to a swing axle. If you didn't grow up driving swing axles, they're a handful when you are pushing it really hard. Same deal with most of our bikes. It's just that I grew up riding them. Swing axles? For me? No thanks! I have a friend that can drive the shit out of them but not me.
Four pot Brembo's? They have to work better than the two pots but I can out brake most all my friends with them. Plus the Mono bikes have bigger, beefier Brembo's than the '81-'84 twins. Less flex and bigger pads. I think they work better.
