help weight my boat

I have an 04 wakesetter and I can't seem to get my wake where I would like it. Seems I have to go fast to get clean wake to wake jump. I am riding at 65 feet and I have the stock bow ballast filled and the wedge down. The wake doesn't seem to be that big. I usually only have a driver and a spotter on the boat so there is not much additional weight. I am thinking my issue is weight and that I need more. Any recommendations would be appreciated on what I can do. I am trying to get wake to wake 360's and I can't seem to clear the wake while doing it. I can clear the wake just jumping. everytime I look at these videos of people doing it they seem like they clear the wake with such ease with all there tricks. I feel like I gotta put so much effort into clearing the wake. I am not sure what the speed I am going since I am not sure if my speedometer is correct rpms I am going about 2400-2500.
