Power-Sonic batteries

I am thinking of either buying one of these. The spec sheet says 6 milli ohm internal resistance.

Here is the spec sheet for power-sonic.

or a Kinetik HC1400.

Which one do you think would be the better battery? This is going as the main starting battery. I looked at both batteries and they both have similar specs. I do not know the internal resistance of the Kinetik though, anybody know it?

Any body heard of Power-Sonic.

do a search for it. i made a thread about it a while back both here and i think on termpro. i only got negative responses about the battery from people like scottie johnson, which was enough to steer me clear of them for a car audio applications.
