I run anywhere from 150-300+ lbs in the bow. I use lead. I can't remember exactly how much we filled it up to, but yeah, we would fill it up to about 600-800 lbs (just a guess) and then the rest with air.
Normally, we run about 150+ in the nose and a 500 or 600 lb sack in the rear. We usually have 5 or 6 people plus gear and cooler and this will make a wake a little under to a little over your knee. With 5 or 6 people, gear and 300 in the nose, 500 or 600 in the rear and two 250 side sacks the wake will be about halfway between your knee and your hip. Granted, I'm only 5'6", but it is still plenty big. I have had people that normally ride on newer boats all compliment the wake.
