Anyone have experience with x -series v-drive sacs

Hi I just purchased the FLy high x-series v-drive sacs and tsunami pump and will be using them on my 2001 Malibu Sunsetter VLX with titan tower and wedge. The 2 sacs are 400 pounds each and I will be putting them in the engine compartments. Will I be needing a ski locker sac or anything else to help level out the boat? Also how much better will the wake be? Is anyone has experience with these bags or pump tell me your thought on them.

Thanks
