Keep in mind that HSB feed more in colder water than LMB. So while the crappie are in cold water slow motion (reduced metabolism) the HSB are still at full speed preying on the crappie. The same type of relationship exists between YP and BG. YP eat a lot of small BG during winter cold water periods while the LMB don't eat many. HSB eat a lot of small fish even when the HSB are big.

I would bet that the SEP approach will work much better than any using LMB.
