Help me pick a clutch for my street/strip Dart- Centerforce Dual Friction Died!

Need to get a new clutch (and pressure plate) for my 68 Dart and I'm hoping for some opinions from what others have run. It's a street/strip car so I put about 2k miles on the street and figure 8-10 sessions at the track.

Specs:
408 stroker (500 hp/540 tq) From 3500 to 5800 it's making 450+ ft/lbs torque at the rear wheels so its pretty hard on launch. I'm pulling the heads off to have them ported and I'm switching to a solid cam so these numbers will go up next season.

• A833 4 Speed 23 spline (70 on up style (not ball detent).
  
• Had a Centerforce Dual Friction and stock flywheel (clutch **** the bed after 1k street miles and about 16 drag passes).
  
• Hydraulic clutch setup from American Powertrain
• QT bellhousing
• chromoly driveshaft
• 1350 U joints
• 8 3/4 with Moser axles, 3.55 (Currently) but 4.10 are sitting on the bench to go in now that the clutch failed and I'm done for the immediate future. Has an Auburn Pro LSD, 489 case with crush sleeve eliminator and the aformentioned 1350 yolk.
  
• Mini Tubbed with 28x 12.5-15 Mickey Thompson Sportsman Pro (Bias Ply)

I just pulled the transmission and the clutch / flywheel both need to be replaced. The clutch stopped holding when I shifted into second at the track on run 6. I coasted through the lights back into the pit. Even though I got off it as soon as I slipped it was 100% shot and wouldn't even move the car on flat ground. (I shifted into second and instead of grabbing it just slipped and I bounced the engine off the rev limiter for a second or two before I could let off).

I'm looking for a clutch that will handle going to the track 8-10 times a year but also handle 2k miles or so a year on the street. I realize I probably will have to compromise somewhere but I'd like to find the best that I can. I called Mcleod already and they suggested their Twin Disc RXT clutch however my concern is that it would be too harsh for the track? I also was looking at RAM clutches both single and twin disc. I'm not afraid to spend money to get good parts but I also don't want to throw money away on a twin disc if its not really going to be beneficial.

I've read about the clutch tamers but my concern would be that its actually hard on the clutch because it's slipping it every time I launch? Would a clutch tamer on one of these street strip clutches be ok or is that more for the race clutches that can handle slipping (sintered iron discs etc)?

Appreciate any suggestions.
