Old thread, but why not keep it going to discuss new (and old) rods that fit the bill?
Had a cast with the S86M. It's overkill for land based longtail tuna, well suited as a kingy stickbait/allround topwater rod though. Unusually nice rod for a shimano!
I bought the RF Aquila 85 recently (the one Sydney recommended) and it's close to perfection for medium heavy land based fishing at spots where you don't need too much clearance! It has a soft tip to cast 60g-100g really well, with a fast taper (handy for clearance and dictating terms land based) and a lot of power down low. The rating is realistic with pe4-6. I hooked two good kings on it, one landed and it handled 10kg drag (conservatively) well. Even though powerful it's still a lightish rod in physical weight coming in at only 340g (most similar rods are about 380-400g). You have to be careful not to bash it around on the rocks though, especially when climbing around...I'm just ordering a new one...
For a long medium heavy LB rod (10'4, pe4-6) I just got an MC Works Raging Bull 104XF-2. Rated 40-140g. Will give it a good workout this season and report.
