Your tension adjustment needs to be calibrated every time you change weights. Put your weight and full setup on, slacking the adjustment so it falls freely. Then, tighten it until your setup goes from free fall to nearly stopping. It's easier to show in person and any tackle store or experienced angler can show you. Within reason, I'm able to cast any line/weight to anywhere with precision without birds nest or too much braking. Minor adjustments may then be made, if necessary, for special circumstance. Practice makes perfect. Hope it's explained right. Just my thoughts. Hope it's relevant.
Cheers!
