By way of the limited comparative info, that sounds like close to 3 times the torsional resistance.

When linked to an equally resistant "spring", by way of the SFIFS...
That would seem to make it more stable as well. I dunno. There is a...gulp...Jeep dealership here in my area that has a club and they have ramps they use for owners to test flex and whatnot. It may be worth a trip for me just to make them look silly as well as gather some tangible empirical data.
