I've pulled a few slalom skiers with my X-star and the wake at 32 is actually not that bad.
Anything slower and it will feel like a deep-V I/O wake. Either way, consider it for recreational slalom use only.
I think the X-2 is a better overall choice for your needs. With the trim plate it should be fine for slalom. You should be a able to find a nice one for under 45K.
I was njskier on here.
