Wake on a 96 malibu sunsetter lx with wedge?

Can someone with knowledge of this boat or has ridden behind one can tell me how the wake is? Just bought one last night and havent tried it out yet til 2morrow...it has no ballast or fat sacs ...drove it for a while at lake sonoma but it was so choppy and windy that i wasnt impress the wake but hoping it was just the water or it needs fat sacs. boat is very clean and couldnt pass it up..

thanks
