Ballast Effect

I am an intermediate rider (backrolls, tantrums, most of the 180s). I have been riding behind my 2003 Tige 22V with no additional weight. I am adding 2000# of ballast this winter, what can I expect from this? Also, my friends who ride with me are beginners (working on wake-to-wake) will the additional weigh help them progress or just intemidate them?

Any advise would be greatly appriciated.
