Keep original plants from seeds for mums or is it ok to keep the offspring as mums?

I’m starting a pheno hunt with a couple of strains. Is it better to keep the original plants that grew from seed as mums or can I use clones taken from those plants as mums? It would be quicker overall to do the latter, but I want to preserve the genetic qualities of the strain as best as possible.

Either way is fine.

I don't keep dedicated moms - always cloned the clones. No issues.
