This is really comparing apples to pears.
Torus and LCD wings have different lift capacity, and if you go by Tobins advice to choose the smallest wing applicable for the type of dives you do, you really don't have much of a doubt there, just select the appropriate size, form doesn't really matter.
I dive an LCD30, switched to it when I had 45 dives total, from a jacket BC. No problems, but also not going back to jacket BC, ever.

Both are excellent. I'm a fan of donut wings, so I would choose Torus given a choice, but I'd be happy with either the LCD30 or the Torus 35 (both designed for single tanks... and the Torus 26 is not quite beefy enough for me).
Can you explain what you mean by the Torus 26?

I pretty familiar with these wings
The reality is there is very difference in how our LCD wings dive and perform from our Torus wings.
How can this be? You probably have been asked to believe that donut or full circle wings are "magic" defying even the laws of physics.
Not true, gas still goes to the highest point in a wing......not likely to change anytime soon.
Consider the horizontally trim diver with a partially filled wing. Where is the gas? In a bubble running down either side of the tank. There won't be any gas in the top arc of the wing, and in the case of a donut wing there certainly won't be any gas in the lower arc. The lower arc of the wing is the lowest part of the wing. It's trapped below the lower end of the tank.
Now if your wing is properly sized for the application, and is a narrow center panel design the wing can't wrap up around the tank very far, and the "bubbles" on either side of the tank will be nice and low, about mid way up the sides of the tank.
To vent this wing via the fill hose requires you "chase the bubble" into the top arc of the wing by slightly raising your shoulder. To vent via the OPV on the divers left will require that eventually you move some gas from the right side to the left side of the wing.
This balancing can be accomplished two ways, via the top arc of the wing, same as dumping via the hose, requires a slight shoulder raise, or via the lower arc of a donut wing. To get gas into the lower arc of a partially inflated donut wing requires that the lower arc be the highest point of the wing. Remember for the horizontally trimmed diver the lower arc of the wing is usually the lowest point. In short you need to go butt up.
When does a horizontal diver vent a wing? During ascents. I try to avoid butt first ascents
If you are diving a Drysuit, or plan to remember you need to vent the suit also. This requires a shoulder up, not butt up attitude. When you vent your suit, a narrow wing will automatically balance through the top arc.If is all true why build any donut wings? Donut wings do allow the designer to "hide" a small bit of the wings capacity under the tank. This allows for a slightly more streamlined over all profile.
Having said that the single most important factor in reducing drag, and providing ease of venting is getting a wing that is large enough for the application, but not over sized.
That's why I recommend using what ever wing we offer that best matches your application whether it is a LCD or Torus.
Let me know if you have any other questions. I'd be happy to size a wing for you.

LOL!!
I knew it was the name of the product, I just ordered a Torus 26. I was wondering if you meant beefy by not being as well made as the others.
