My surf tabs are set between 50 and 65 on each side depending on weight in the boat. before a run, I will usually adjust the tabs to where the wave looks good.
Things that contribute to a longer wave are increasing speed, increasing weight up front, and putting the tab down. With a longer wave, you usually don't get as much push unless you have a good amount of weight all the way around. I have Enzo bags in the back, 700 center, 500 IBS, plus I put another 400lb fat sac in the front playpen, speed at 11.3 ish and tab at 1/2 to 3/4 and I list the boat a few degrees to the surf side using the rear sacs. My wave is about 5 feet longer than the rope and has plenty of push for my 6' 180 lb frame, but it has a pretty steep transition. Still working on a mellow wave with enough push for me to do more spin tricks...
