Huntington-Hill is better than nothing but it is still significantly worse than getting rid of the PAA and letting the House grow based on population size. Pressing my hand down on a bullet wound will slow the bleeding more than if I didn't, but not getting shot to begin with would sure be preferable.
This argues for just an increase to 700, and shows a ~5% swing in likelihood of Democrat control, and I would argue that just increasing it to 700 is still not where we want to be - a ratio similar to the UK would put us at closer to 3k representatives, and I believe this is still within reason (and is roughly the size of the equivalent chamber in China). Ideally we get rid of gerrymandering at the same time and redistricting is done apolitically by independent groups.
At 3k seats, every state is above their 1 rep minimum, representatives have 1/7th the number of constituents, population to representation at each state is much closer to 1:1, etc. Obviously not everything will end up on clean divisible lines so there's going to be some differences, but Wyoming would be more like .96:1 instead of .75:1 like they are currently.
Ideally the size should also be set to be revisited based on population on a periodic basis
