A pole limit would only effect the time it would take to reach your limit, as does using the newer electronics on the market would. Think about it, the guy with a 20yr old Jon boat pushing 4 long poles may be as efficient as the guy with 2-3000$ of electronics, so not much difference in time on the water. I see it as just another method of crappie fishing.
I for one never keep my limit, but enjoy the extra action.
