The official responses from Oxycheq:
Question:
"The travel plate wouldn't be "floppy" under the load of the Steel 100 or Steel 120? "
Answer:
"If you are referring to the Ultra Lite Plate, that wraps around the cylinder and the harness can be made extremely secure."
Question:
"my mistake - my question was in reference to your ultralite plate. I asked because I was thinking of getting an oxycheq rig with the ultralite plate for my dives in South Florida with a Steel 100 or 120, but read online posts that it may not be such a good idea?...

Answer:
"In the one thread, the guy put weights on the cam straps instead of using weight pockets.
In the other thread, the guy mentions the larger cylinder moving around. Not sure how that is happening because the cam straps lock the tank to the plate and the harness locks in tighter than a Hog harness does."
Question:
"I'll get the Ultralite plate then - I just need to avoid putting weights on cam straps? I should be able to slap on a steel 120 with no issues? For tropical diving (with a large tank) the aluminum plates would offer no advantages over the ultralite except for the 2 lbs off my weight belt?"
Answer:
"If the cam straps and harness is snug, I see no reason why it would not hold that size cylinder. Certainly, it will feel different on your back than a plate.
Advantages of an AL plate is that it will last forever. Adantages of the UL plate are ... lighter, less expensive and the harness system actually fits much better than a Hogarthian harness. It is also easier to get on and off and much easier to adjust going from one type of thermal protection to another. "
I'm pretty sure that a soft back plate will never be more stable a platform than a rigid black plate nor is it suitable for doubles. I rather get a hard back plate any day.
