torium 30s are nice reels, lots of good fish caught on them, matt watson got a marlin on his torium.

One of my first setups was a torium 30 on a Ian Miller 400 T-Curve, did the job but got smoked a lot. If your not fishing wicked structure them nothing wrong with them for an entry level set. Still got 2 of them now, use them for everything

Fished a torium 30 as an early jigging setup, would say it is alright for minimal big fish action.  The dartanium drag washers will wear out quickly under continued heavy use.  Will need to watch the anti-reverse as well.  Shouldn't be as much of a problem from a kayak as you will probably be using lower drag settings.  I use mine as a snapper reel now.

What about a Daiwa 30T ?

I've got a torium 20 that i use for jigging with the 200gram rod. I use that off my kayak with 15k braid and 5-6 k of drag is more than enough - i really wouldn't want to go much more i reckon. Especially off a yak. If you match it up with pe3 or pe4 braid and chuck it on a 200g/300g rod it would be a great combo. The torium 30's one and only advantage over the 20 is that it has more line capacity, and really if you're spooling it with braid (even 50lb stuff) the 20 has more than enough capacity for any fish you're likely to catch off a yak or in the gulf. Also the 30 has a wider spool than the 20 which in my opinion does make it a bit harder to jig with.
