What DG said is certainly true. But if you have the money, there is no substitute for anti-reverse on a really big fish. I really like my Billy Pate for such situations. This becomes more true when you get tired in the fight and are just holding on to get your strength back. You do give up rim control but you can reset drag at will - and it is a good one.
Otherwise, Litespeeds are good as well as any Ross. Many more to choose from, all good.

Godspeed,

Bob
