That's a angle you could definitely take. I have thought about it. But Devan makes a good point too. It all boils down to what you want to consider bigger.
LeBron James is 6'8" and weighs 250lbs. So if he was 5'2" and weighed 250 he would be just as good? I know that's a silly analogy.
But we have associated fish with weight for so long (tournaments, records, lies) it will be hard for most to move past that. But those Kayak guys are doing it with ZERO issues. Yeah they have some cheaters there too.
