Looking for everyone's advice on my surf set up since I'm a beginner to the sport.

Yesterday I had 750lb ballast on the surf side and the factory 400 in the center ballast filled in the video below. I also had quit a few people in the boat adding bit of weight, I had one adult (approx. 200lb) in the bow, 3 adults on the surf side approx 500 lbs (do the math and one adult in the back on the non surf side (when I had him go to the surf side I thought we were going to take on water). It seemed at about 11mph I could feel the push more, we ran between 8.5-11 during the session.

Looking advice on speed, position and weighting after watching my video. Anything helps. Thanks
