Well, I got curious and wanted to see if there was actually an internal difference in the Torium 30 and a Trinidad 30.
The schematics for the torium are here

for the Trinidad here

The Torium's antireverse is pitiful. I have witnessed it failing w/ big fish myself. I have not witnessed it with a Trinidad though- only heard of it through others.
Interestingly, from the schematics, the two reels use identical anti-reverse systems. This could be in their 2007 models only, but I am getting to my point. See part #'s 294, 303, and 306 in both parts diagrams. Also notice that the reels are identical except that the Torium's frame breaks down into one less piece than the Trinidad and that the Trinidad has an adjustable clicker and centrifugal braking system. Another interesting aspect is that the trinidad has a spacer and extra "gear" as it is called in the parts list and an extra spacer. See part #'s 317 and 769 in the trinidad diagram.
This is the absolute only difference I see in the two reels' drivetrains - two small parts! Unless the toriums are just built with sloppy tolerances for the anti-reverse pawls to get mangled.....
Shimano lists the Trinidad 30's drag at 16.5# and the Torium 30's at 20#. I do not understand why the Trinidads retail at over $300 and the Toriums retail at under $200. Could it be the Torium's diecast and painted aluminum frame and stamped metal sideplate cover vs. the Trinidad's anodized diecast bling, casting brake, and variable clicker? What exactly is the deal?
Seriously Shimano.
