It's really user preference. Fast is the most realistic, but it will take time to build the muscle memory/ hand- eye coordination. Normal is a nice happy medium with more fluid /smooth animations. Flazko likes Normal the best, but he also likes the realistic nature of Fast. I'm thinking Fast with All-pro will be a nice combo. Best of both worlds/ more realism in all pro, but you'll get more challenge with a faster game speed, whether it be normal or fast
