Welcome.
First off, IFS (Independent Front Suspension).
Just like TTB(Twin Traction Beam)
As far as a straight or solid axle, I think those terms are interchangeable. As in a rear axle is a solid axle.
Like I said, I think that the terms are interchangeable. If I see something else about them I will post it.
Good luck in your quest for knowledge.

The Ford TTB was a modified form of IFS, still an IFS system though. The F350's from 85.5-97 used a dana 60 solid axle, rather than the TTB the 80-96 F150(coil sprung) 250/80-85 F350(leaf sprung) used. The 97-Up F150's and the F250 LD(looks like an F150 with 7 lug wheels) run an A-Arm IFS, while the Super Duty trucks(F250 HD and up) use a Solid axle with leaf springs, either a D50 or 60 depending on the truck.

Ford TTB front axles are basicaly a solid axle that pivots in the center that makes it what I call semi-independent. The Caster and camber changes as it compresses and rebounds. The newer 97up F-150's have an upper and lower control arm that keeps the caster and camber in check. I have a 93-f250 with TTB, if your really load it down the front tires lean in. Ford kept it from 1980-1997 F-250s, There is alot of parts available for them and that is a plus to the added tire wear factor.

A TTB is a FULLY independent suspension. There's nothing "semi" about it. It's just as independent as a twin A-arm or a MacPherson strut setup.
Any independent suspension becomes "semi" independent when it has an anti-sway bar on it, but you'll find them on any type of suspension.

Straight and Solid axle differances
When looking at solid/straight front axles on Fords, generally the lighter duty models (F-100 F-150) have coil springs and the heavy duty models have leaf springs.
The more durable and easier to modify (read lift) are the solid axles with leaf springs, they provide a lower cost of repair/ownership over the life of the vehicle. Also, they provide the worse ride and handling (they do not feel like cars or minivans).
You can not have everything :-)

IFS stands for Independent front suspension. So a TTB is that, because both sides move up and down independently. There's no such thing as modified IFS. Come on, common sense. Some IFS are better than others, but just because the TTB doen't have two control arms doesn't mean it isn't IFS or is "semi" IFS, because both sides still move up and down independently.
