Too right that is a good bass The biggest bass I have ever seen was caught on a bubble float and a small redgill Just over 14lb when weighed in. But, if you want to catch big bass consistently forget redgills, use live mackerel. Boat or shore it does pick out the bigger fish. There are always big fish caught on a variety of baits every year, but these fish are the exception rather than the rule.
It has always been my way to try and match the bait to the size of fish you are fishing for feed on, it does not always pay off, but I believe it puts the odds in your favour. Sometimes it works,
