THe determining factors for me are how fast they hit the ground, and how fast they hit the ice.
Push either of those and you end up with gamey pork no matter how big they are. That said the bigger they are, faster everything else needs to happen.
I have had some that bumped 400# that were excellent, and some that were 30 ruined my supper. I just learned as I went and found the faster I can drop them which isn't always in my favor, and the faster I can get them dressed out and on ice or in the freezer the better they eat and I don't pass on many at all.
