Hi Sachin,
I've not long returned from a 2 week stint at the Diamond Islets with Nomad. Loads of doggies, lots of experiences and wonderful memories, including one of our guide with Nomad, Glanville prancing around on the deck of Tide Stick in a storm of spray and rage, all hair, teeth, and eyeballs, seething and foaming at the mouth, expounding every form of expletive ever muttered by man, or even by an enraged rabid South African strain of Tasmanian Devil in the midst of an apoplectic fit, after my companion Micheal got bricked in spectacular style by a leviathan of a doggie that probably went well over 100kg. It was one of 16 that we wrestled on that day between the 2 of us, and we only managed to land 2 complete Dogtooth, all the others were either sharked or just plain bricked us. But I digress.
If the rod fishes 2-300g well and can handle at least PE6, then it will be able to lift the fish in the water, if at least with a little care and no high sticking. A PE8 gives you more power, but it won't stop them from running, and generally speaking will loose some of its lighter jigging weight range. You won't stop them from running, no matter what the rod-you will be relying on the drag output from the reel, and a Stella 20k is as good as you can get with the most drag you can probably still handle. From what I have seen, I would say that if you hook up on a really big dog then your in big trouble any way no matter what the gear. In the two weeks of doggies at the Diamond Islets, there were only three rods broken on a couple of hundred hook-ups, no doubt all due to high sticking.
Sounds to me like Scott's suggestion of the Hots Wei World is as good as any for the job on Dogtooth. The Smith AMJ, and the JM's are also proven and will also do the job just fine. For myself, I am quite happy with the JM's, and I am adding a few more with the addition of a couple of JM Three King Specials to my collection.
