Zpack or regular Borg Warnrer Clutches for 3/4 pack?

Dana at Pro-built sayd they're the same, but he offers the Z-pack instead of the Borg Warner clutches for the 3/4 pack in the 700R4's.

What do you all think? He hasn't shipped my kit yet so I still have the option. Any and all comments welcome!

ZPack.
I have a few cars running them deep into the 10's with no failures yet.

I offer the modified Z-Pak (16 clutches instead of 14) in some rebuild kits. I also offer the Borg Warner Hi-Energy clutches (8 clutches) in these same kits, it is just an option of what you want to use, the BWS Hi-E's or the modified Z-Pak. It is a "sideways move", not an up or down grade in the particular kit.

That's what you had said over the phone, I was just looking for some input from people that have them in their cars. The Kit i ordered has the BW clutches, still waiting for it in the mail. Looking forward to getting this rebuild underway!
