Understand now. That topic is still the same as far as I know. There are different opinions on the topic. My opinion is unchanged and I have seen no new data except as follows.

Here is one genetics study in TX (integrade zone) finding all types of Fla-Noth mixes and no mention of outbreeding issues.

We found no evidence of a heterotic effect (in terms

of size) resulting from first-generation crosses between

Florida largemouth bass and northern largemouth bass.

The majority of trophy-sized fish with an admixed

genome were later-generation hybrids with a larger

percentage of Florida largemouth bass alleles. There

was also no observable negative impact on size from

the admixed genetic background in these fish, most

likely because of the modified environment to which

they were introduced and the nonadaptive radiation of

micropterids (Near et al. 2003).
