Alternatives to KYB?

Here's a clip I made earlier of my Dart with KYB frontshocks and 1" JustSuspension torsionbars. Not the best video to get a good feel of how the car's suspension is working but I think you might get an idea.

I currently have stock torsional on a 72 cuda, small block, with KGB and hate it. I was thinking of summits 0.97" bars. Will that help the KGB or should I change to Holstein?
Forgive spell check, u know what I mean.

I have Hellwig 1 1/8" in front and Hellwig 1" in back. I just installed the Bilsteins from PST on Friday and drove it most of the weekend.

IMMEDIATE difference. My KYB's pretty much bottomed out on any bump, pothole or crack in the road. It was as if it shook the entire frame of the car right into my spine. After getting Bilsteins in, the ride was SMOOTH. Going over the same bumps and potholes on my normal routes was a breeze. This was a worthwhile improvement. Would it be better w/ Hotchkiss? Eh, who knows. But it definitely was a bit hard to pass on the deal w/ PST.

I'm happy with this upgrade.

UPDATE: I no longer have to slow to a crawl when crossing railroad tracks.
