There are some people that are purists and consider any crossing of different locals hybridization and that's fine its just there views and not based on science. This was brought up in a conversation with a guy in AU who goes crazy when he sees people crossing carpet pythons of different locals (jungle carpets from Sidney to jungle carpet from Queensland). Its the same species bred to the same species from a different local and they feel it is wrong because it took thousands of years to get those particular traits to adapt to that particular environment
LOL that is me
but i will cross the heck outa leopad geckos lol
but if i get pure local ssp. (in boas especially) i make sure of what i am getting and who i am getting it from (which are only a handful of people). now, dealing with the leoaprd geckos i do not know who collected them and how many peoples hands have been on them and if scale counts have been done, so it's not as big a deal, but i will keep a diversified bunch of "ssp" leos and breed them together to keep good strong lines and also out cross them to clean up other lines
