Which older V-drives handle rough water best?

I am thinking down the road to my next boat. I may be moving to Las Vegas and I know Lake Mead can get rough at times, or I may need to travel through rough water to get to good water. I currently have a 1991 Malibu 20.5' Sunsetter DD with an open bow. It works great and throws a really nice wake with the weight I am using, but it doesn't like the rough water. I have to keep it below 25-30 mph in rough conditions. My previous boat was a 20' Bayliner I/O and I could travel 40+ mph in rough conditions and it did well. I don't expect any wakeboat to do super well in the chop, but I would like to get people's opinions on different v-drives in the rough. I plan to look for a V-drive; quality of the wake is #1 priority. I will be looking probably in the sub-30k range, and would like a boat that is new enough to have EFI. I was thinking about mid-90's Super Sport nautiques, but I couldn't really find any reports of how they do in the chop. Any thoughts?
