Hmm...never bent the shock shaft of a 12R5. And I'd be one to do it!
Anyway, of all the shocks you mention, I'd say the CRC. It's readily available, builds up smooth, doesn't leak, and fits AE springs no problem. It's red, which may cause some cognitive distress once mounted, but there are drugs for that.
Pity about the Hot Bodies shock. It seems to be gone from global inventory.
