I use one of the new(ish) saltist lever drags. i have a 40 but you can get one size bigger. I have the 2 speed version which is handy, low gear for winding big snapper leads up from the deep. High speed for winding up the light weights. I recon constant big weights will kill the bearings over time but not hard to replace when/if it happens.
Talica's are similiar and nicer but more expensive.
