Torsion bars for better handling; your experience?

If you replaced the shocks with solid struts you would have no suspension at all, the springs wouldn't do anything...??
Which models are those? I want double-adjustable shocks so I can buy one set and use them forever even if my suspension setup changes which it definitely will. I don't like the idea of non-adjustable shocks where you have to match the spring rates, vehicle weight, tire grip etc. to the damping rates or else you're losing performance... (????)
You still have to be cognizant of the range on an adjustable shock. Just because its adjustable doesn't mean your idea rate is in its range.
Bilsteins, Fox (Hotchkiss and Ridetech) are mono tubes. I don't know of any off the shelf double adjustable shocks. You have to decide if your setup warrants spending 1500 and probably more for a true mono tube double adjustable shock. My guess is no.
