take Johns advice he is the kingie master
you wont be able to push 13kg of drag into a tcurve so dont worry about big drags
the gosa would be a great reel for that outfit spool it up with some pe3-4 and u will have a nice little combo
i dont think the smaller gosas come with carbontex drag washers so u might want to upgrade to them if thats the case for a smother drag
you dont need big drags and heavy rigs to catch big fish i no ppl who pull 1mtr+ kings jigging in <30mtrs of water using pe3 outfits
