Two questions: 1. Regarding Note #3 directing the user to always use Berk. Big Game line diameters. Question: Is there any reason I can't use the exact line diameter from the manufacturer if they specify capacity in MM line diameter/Meters Capacity? I would just need to convert millimeters to inches and meters to yards correct? 2. The calculator is designed for Copper/Lead core mainlines. Can I use the calculator to estimate a reel set up with mono backing, braided mainline, and flourocarbon Leader? Is there something to the calculations/formulas specific to copper/leadcore lines?
