Hi Ken,
I have the PHD Alpamayo smock and think it is the best waterproof I've ever had!
I've put a recent review on my Blog: Gordon's Off.
And, my original - first impressions of the Alpamayo is on the Blog too.
I looked at similar jackets to those you are considering and found them unable to match up to the Alpamayo: either - not the right fit, too short, too flimsy, elasticated cuffs, insubstantial hood etc.,
The Alpamayo is a proper 4 season smock.
If you are concerned about PHD sizing/fit you could ring PHD and they may be able to make sure you get the right fit.
I know I'm biased in favour of PHD, but the reason is in the quality of products!
