Hey Jordan, heres that website I was telling you about that determines line capacity by line diameter. Just put in the specs of the reel capacity and then the diameter of the line you want to use.
The reel you mentioned held 170 yards of 20lb test or .018" diameter line. You want to know how much 30lb test, .022", it will hold, just use the chart below on line diameters to calculate how much your reel will hold. Hope this helps.
