Traits Mayday line & Frisco line

Hey guys just wanted to see if anyone with hands on experience would give their thoughts on the traits of the descendants of these 2 great dogs and what traits they bring as crosses into other lines. Obviously in 2022 these 2 dogs have been dead for decades but still have descendents that are extremely popular at this time so experience with those modern strains are welcome. Some example are the Dynomite, Simba, Elmo lines as well as Barracuda, Hogg, Puma, Machobuck lines. Thanks for any input.
