I feel weight classes should be changed!

There is little to no difference between the minimum weights to flyweight... some are only by three of four pounds. Useless.

As a percentage of body weight it is not that much different than all the others up to Light Heavyweight.

But how was that measured? Is it effective weight? I dunno?!?! I don't see a big difference between a guy fighting at 105 and 115. There isn't that much difference.... jmo....

My point is (using your example), a 105lbs man has put on 9.5% more weight to get up to 115lbs. But a 160lbs man only needs to put on 6.25% more weight to make 170lbs. That is why there is a smaller gap in the weight divisions at the lighter weights.
