I've been looking at the Salina 3 also. I have a friend who swears by them and has a few and they get a workout, believe me. Big kings, GTs, spaniards etc off the rocks. But the point made by Roylo^^^ is a good one...speed isn't everything, sometimes torque is more important for big fish...especially when you're not in a boat that can chase a fish down while tiring it out. 15 kg drag is ample and line capacity??? If you've lost 300yds of 40-50lb line on a reel with 15kg drag...then you're pretty much burnt anyway!
I like the reviews and specs of the Pfleuger Crank and Salt reels....seem like good value for money. I have a 40SW Salt and it's as smooth as butter and spooled with 15lb braid, it's got some gumption too! The Penn Spinfishers have a good rep, but only 4.9kg drag...a little light-on by today's standards. Still, a fairly bulletproof reel.
Shimano Socorro is a good reel, but the drag pins are known to break and I don't think they are covered by the warranty, so it's like a $60-$80 repair...so...good luck in your choice.
My money's on the Salina 3, and they are available at WELL below retail if you know where to look! :-)
