Rich, set the drag for around a third of the breaking strain for braid, so about 5-6lb would be good. This will also depend on the rod, for braid they are not as stiff as others to compensate for the lack of stretch in braid. Err on the side of safety mate. You dont really need the spool brake for sea fishing but if you want to set it up. attach the relevant lure, weight etc and adjust the brake until it drops at a steady rate from the rod tip. The spool brake is a casting aid mate, rather dodgy with braid on a multiplier coz if it birds nests you can kiss it goodbye. There is no problem using a fixed spool for this type of fishing Rich. That could be a way to go, especially if you use a bait runner. Regards, BB
