There is a study on how Fla LMB did in OK. It was so-so on the results. But F-1s should do fine in your location. The proof is in this pic which is from a hatchery in OK and these are F-1s.



I would call them as they often have larger F-1 for sale and they are acclimated to your climate.

Also you could call the Pond Boss office and talk to Bob he may have them and has used Inslee for F-1s.
