I have seen the Hardy videos and they continue to impress me. The new Fortuna X reel that will be released in the near future is capable of up to 32 pounds of drag force in the largest size. You will need a rod as strong as the ProAxis if you tighten such a strong drag and go after spinner sharks. It doesn’t hurt to be a champion tarpon fisherman like Andy Mill either.
The footage below shows an angler fighting a shark on a Hardy Sintrix 9'6", 7 weight rod. The torque that is exerted on the rod during the fight is amazing. It would be interesting to see some of the other high end nano-resin rods put through the same fight.
The video aside, what drag force is normal on a reel for a saltwater application? The Lamson Vanquish can apply up to 20 pounds of torque. From my reading the Vanquish and Fortuna X are two of the strongest drags on the market. It seems that anglers can use much lighter rods and target larger species with some of the new technology that is emerging in rod building, provided that the lighter rod can cast the large flies that may be required.
