BR7 or AR93, which is colder

My truck currently has the BR7's in it but I have a set of AR93's on my work bench. I am thinking about upgrading from a 4# on a ported blower to a 6#.

According to the charts the AR93 is one step colder than the BR7.

I ran the AR93 for a while and the burn was cleaner than what I have seen in pics of the BR7. I think it has to do with the cutback design. The idle quality was every it as good or better than the TR6. The gap is small from the factory so I opened it to .032".

I hope this helps you out.
