I may be odd man out, since I started riding and racing back in the days of carburetors and no computers.
I've raced bikes with both standard and slipper clutches, and I prefer them without. Same goes for traction control, I don't like the way it nanny-fies the bike.
ABS is another story.
Learn to feel the chassis and engine, and what the bike is doing. You will be far faster than the guy who learned by letting the bike ride him. Just ask the guy I smoked on a local bit of twisty yesterday on a new panigale. TC kept neutering the bike. I'm on an '04 Z1000. Long sweepers where he could maintain speed and he was gone. Anything tight and I had him.
