Side by side by side by side is the only way to really judge a boot effectively in my opinion. I agree with you on the Hanwags although I prefer the Mountain Lights, and also on the Lowas, great boots (and they are avaialble in Wide).
Not a Cabelas Meindl fan, although I like some of their German models, they are too hard on the bottoms for me which was only revealed after 10 or 15 miles out on the mountain under a load. It gets expensive but I have found after testing hundreds of boots that the personality of each pair only becomes truly known out on the trail humping a pack up one side and down the other.
Ambiguous on the Kenes, certainly not bad but I've found others I liked better.
I am an Asolo fan (FSN95) but I don't think that the Sassalong is offered in the US anymore, but I could be wrong, which is too bad because it was also offered in a Wide version.
I think that those Zams are too soft (they remind me of Crispis in that respect) and flexible for a boot with a full rand.
The other two boots I like in that class are Scarpas. The Escape and Liskamm GTX which I rate right up there with the Lowas and Hanwags.
But, like you said it is all about fit. Nice job.
