Driving in circles

I found the only way I can surf is to be doing never ending circles depending on the person's stance. My boat is a 2000 MB Sport DD. I usually have to people sitting on the very back of the boat, 2 full barrels of water, and two steal plates, my ballast full, and maybe another person sitting on the dog house totaling about 1000lbs. Now the wake is fine for me to ride even though I am 6' 220lbs, the pocket is a bit smaller but I'm doin alright. The only way I can get a good wall to ride is doing a farely tight turn to either the left or right. Do any of you have the same problem?
