Two local speed shops recommended the LS7 for my H/C 03Z DD w/ 451 rwhp & 405 ft./lbs.
However, one of them suggested going with a lighter flywheel and one recommended against going with the light FW. I went with the LS7 fw and new slave and bearing.
I did end up with a very slight vibration
No biggie.

I have had good results from the ACT single disc mated to a RAM billet FW. I think it's rated to something like 750 lb/ft. No chatter at all ever and it will hook when you let it out. I've got 350 lb/ft of torque at 2200 RPMs and I peak at 460 lb/ft. It has performed flawlessly. It does have a heavier pedal than the stockers.
I give the ACT

I have one and it chatters like a cold dog. Ive got 10-12000 miles on it, four years old, and first gear is starting to slip.
It grabs great, but chatters off the line.
I had the LS7 clutch for a couple months and it was sweet, till it crapped out on me

Which textralia do you have? i have the OZ700 with the z-grip disc which I have heard doesn't chatter like the x-grip. I don't know if mine chatters or not yet as my car is still torn apart.

BTW, the LS6 with 30k miles was sticking to the floor after one WOT run. The new LS7 works great. No slippage or sticky clutch.

Bummer dude! I hope my LS7 clutch tdoesn't crap out on me. I have similar RWHP as you with about 30 fewer ft.lbs. I sure as hell don't want to pay for R&R for another clutch. That would really suck!

My tex is OZ700. Grips like a ****, but within the last month or two, I must have burned a spot on the flywheel to cause the little slip onder load. The only bad thing I can stay is the chatter, and that's just the clutch trying to grab and go in first gear.

I Have the same #'s as you - well close 411/399 
I had ECS do my work and they installed a RPS Carbon/Carbon clutch system in the car. WOW is all I need to say! You should really consider this clutch, IMO

I have the Centerforce DF and at its price point it was a no brainer. Both my buddy and I have 450 rwhp and no issues. A little chatter during brake and a nice firm pedal thru the motion really lets you feel what the clutch is doing.
Also i called the CF tech guy and he spent a half hour on the phone with me and i say if you have the time call, he really schooled me on clutches/driving style. Taught me a bunc!

I second Centerforce DFX. A little chatter during break in but drives as easy as stock now and holds my 469rwtq great. I am using the Gripforce F1 flywheel and it only cost $200.
Tip if you use the Centerforce: use new oem flywheel bolts
