i would recommend trying a braided line like suffix. while it will require some adjustment time if you have not used it yet the advantages are numerous and a reel like the accurate boss magnum series will allow you much more the 50 yd cast with line as heavy as 65lb. in concern for capacity i dont have the specs but the smaller series which we have in stock should be able to hold apx 300yrds of 50lb suffix, possibly more. they do make a larger size which allow you any further needed line capacity all in a reel that is capable of putting some serious pressure on big fish...i've smashed many tuna up to 100lbs on their smallest models
hope this helps
