Yes, we have the 28 International, and interesting enough bought it after having a 2005 25 Safari SS.
We are seriously considering the 30 International as we spend 8-9 months a year travelling. I don't think the manoeuvrability will be an issue going from 28 to 30. Just a little tighter in some spots.
Good luck in your search.
