A little off topic...but...when buying line look at the actual diameters, as lb test ratings are all over the place. CXX is rated as one of the top lines in tensile strength -a great line -but it's 8lb is .012, akin to 12lb XL, and most 12lb FC's. Diameter is what affects depth and speed most. That 12lb CXX you were using, at 0.015 is akin to 17#XL, or many FCs.
Just something to be aware of.
thanks , i know that CXX is rated one size (lb.) below what it actually is , for example their 10 lb. is the same as others 12 lb. , but i do know that most mono and co-poly lines that are 10 lb. are .012 so it's not a big deal . i like using 8 lb. CXX cause it is like everyone elses 15 lb. line , but still has a 10 lb. line dia.
