Automatic Transmission - Which Power Band? Alto Red Eagle or HP Carbon?

Getting parts for my trans and the Alto's Red Eagle is $26, or their HP Carbon is $31. Trans won't see more than 350hp/tq, but I want to make sure that if by some chance I come across a boatload of money (hah!) and I do get into the 350-375 power range, it'll handle it. That and I'm just going for longevity, so if $6 nets me the ability to thrash on the trans harder with out a worry, then I'll be happy to spend the $6 :)

Red Eagle:
"New Alto Red Eagle Power Band - 60% thicker band anchor for HD use - 2 5/8 inch wide
Alto # 057961"

HP Carbon:
"New Carbon Power Band - Thicker band anchor for HD use - 2 5/8 inch wide
Alto # 057961C"

Hoping to order the stuff this eve, or at least by tomorrow afternoon, but I'll surely wait for answers!
Thanks,

Either should suit your needs without issue,

You know if this would be recommended?
"TransGo 700-R4 200-4R High Rev pump kit (over 5500 rpm)
TransGo kit: 1 priming spring and 2 hardened steel vane rings"

Just trying to find extra bits that are not costly, but would be a smart thing to install. Seeing that it's only $9.

This is what I'm looking at thus far:
N74020CK Band 700 / 4L60E Power Band - HP Carbon $31.22

74002CF Overhaul kit, 7004R / 4L60, 1982-UP, Fiber pan gasket COMBO $31.91

A74100CPPK Friction & steel kit, 3-4 Powerpack clutch kit, 700R4 / 4L60E, High Performance $90.50
High Performance PowerPack includes: 9 Red Eagle .062 frictions, 8 Kolene steels .076, 2 standard Kolene steels, 1 top backing plate, 1 custom sized snap ring.
(decided this over the Raybestos Z-PACK @ $65. Worth it for a 98% stock motor?)

74241A Washer, 4L60 / 4L60E, Reaction shell. Special design washer for the Beast Shell (which I have). $1.05
