glowball, I have to agree with your comment from someone about northriver. We looked at Alumaweld but got turned off by their unwillingness to do a few custom things. They both have good web sites.
From looking at them they are both built well and
designed well. I liked the 4 inch wider bottom on the 20 ft NR. You have to go to a 23 with AW to get more than 72 inches. The NR is a bit heavier because of the thicker sides but then you hsave more planing surface with the wider bottom. I doubt a guy would go wrong with eather. Another
thing to keep in mind is that in time you will probably go 4 stroke if you haven't got one now.
We want a 225 and the darn thing weights 600 lbs.
The NR will take it, prop or pump. I have sold myself over the last year or so and got help from the guys on the board. I am biased to NR but you should look at both and go with your own judgement.
It's your money and you are the one that needs to be happy. Good Luck
