The First Ten Minutes Offers Your Best Shot at a Big One – The bigger bass will be more dominant in a school, and even if they're not super hungry, their alpha predatory instinct will likely key them in to your presentation early on. Once a big bass bites (and subsequently some smaller, less-educated bass start to be caught out of a school), then the remaining big ones often shut down because they're over-stimulated. The remedy for this is to leave for a period of time, let the school regroup, then return with a full blitz for another ten-minute session. I like to wait an hour before returning. I often see anglers sit on a school far too long. Even if they do continue to catch fish, most likely it's the remaining dinks that are taking advantage of the alpha bass watching the show without participating.
