Got mine today, 6A Ballyliffen and 3A Dunglow.
After fear that I might have sized too small, it turned out to be almost the opposite. For reference, I'm 6' 2" with a ~38" chest - I ordered both cardigans in size 38, but specced with 1.5" longer sleeves & body than standard due to my height.

I'm pretty happy with the 6A myself, fit is pretty much as I wanted.
The 3A OTOH is a bit short in the sleeves, but I imagine you could stretch that out if you'd want. What bugs me more however is that I was aiming for a tight fit, but this one is pretty loose in the body for my frame. Not like the 6A is skin tight, but the 3A is definitively even less so, feels like there's an extra 10 inches of fabric at the back of my waist in the way of a snug fit. C'est la vie, have to figure out what I will end up doing with it. Sleeves are really tight on both, but they give out.
For reference, the P2P on these are about 19,5-20".
