i think your mad ,for rough ground a big fixed spool will get your gear up and out of snags twice as quick as a multi ,you will also find it wont add more than a few yards to your cast ,i use both but would always go for a big fs for rough stuff

those reels look like an abu

they even copied the new look star drag (i think the old style looked better

)still if they cast well and last good luck to em

as paul said 525 for rough stuff its prob unbreakable
try to get a second hand one or you could get one of these
