I previously owned a 2000 Air Nautique, which I am sure you are aware is the same hull as the Sport Nautique. Went from that to a 2007 Ski Nautique 196 and immediately noticed the wake at slalom speeds 28-34 was quite a bit smaller and softer on the 196. So, to answer your question, the 196 is much different wake-wise than the Sport - a lot more friendly. If slalom is your primary use for the boat, I would definitely recommend staying with a 196.
