Well maybe you use bigger plugs more, as you now have this theory. Plus it depends what you call small and what you call big. I have had pike to 30lb+ on very small spinners, plus when wobbling baits, i find the smaller produce quicker, and just as good fish..
I fish a privately owned loch on an estate in scotland. You cant tempt a fish with a lure over 8", everything falls to small stuff, strange i know but true...
true mate used to use them alot on are canal and do good on them but water was very coloured ,jerk bait about 8 inch and get small jacks in the plenty ,another lake i
