I run with one regularly on our lake, which is 17 miles long, and tends to get rough in afternoon. My Sonic runs better in the rough, but I have to admit the Donzi is a very sharp looking boat - love the lines.
If you care at all about the cabin space, the Donzi may not be your best choice, either - Sonic Prowlers have about the largest cabin in the 25' class, and include an enclosed head. But, if you are like most buyers in the 25' class, and cabin is just a space to store stuff, the Donzi has alot to offer in other areas.
