Black Ice Stealth or Xtreme? (Urgent)

[Alexinator]

I'll be ordering my new water cooling system in about 2 hours, and I'm wondering which rad I should buy. I like the stealth version because it's smaller and the non-xflow is a double pass smooth looking one and I think I'd rather get that. The price is slightly higher so I'm hoping that also accounts for performance.

Question is, what are your opinions? have you heard anything or used any of these and could you provide any info that would help in my descision?
