I commonly see PS stunt in ponds where they are not properly managed by LMB. Every pond is unique though, like AP's pond.

RBS and LES have similar fecundity of about 8,000-20,000 eggs. They spawn once per year. The RBS maxes out at about 11" with 8" being big and 6" being typical. LES have a few very distinct subspecies, some even split them into separate species. The northern subspecies gets larger, max size is about 9" with 7" being large and 5" being typical.

I like RBS because in nature, they are commonly found in the same habitat as SMB. If you are fishing a SMB river and you switch to a smaller bait, you'll likely catch RBS in the east and LES in the Midwest. RBS are not as rounded as BG, meaning a smaller mouthed fish can feed on them. RBS can still attain a quality size with 1 pound fish not unheard of.
