yep... if you have a 300 yard spool, spool it on to your 704 1st. when you get all the line on there, tie on your backing and fill your 704 up to the top. then take all the line off of yoru reel somehow, i used a funny contraption i made on my cordless drill and a spare 704 spool.. then flip the line... tie on the backing and re-spool...
should be perfect
