Areo Skis in Brooten MN does not have a web site. Their phone is 320-346-2285. Call and talk to Troy Reese, he knows everything about aero skis.
I bought the M2000s with 3/16" poly bottoms this winter and have them on a stock 170B.
The 2000s are 12" wide, 67" long and 20lbs each. The total weight of the installation was 62lbs with all the rigging and poly bottoms.
The 3000s are 16" wide, 72" long and 29lbs each, no poly.
When I bought the 2000s, there was a pair of used 3000s for sale on Barnstormers. I talked to a couple of experienced skis pilots that recommended the 2000s are a better match for a stock 170 in the snow conditions here in central ND.
I believe a stock 170 with 3000s in deep powder would struggle to move. And in the air the 3000s would be noticebly more drag.
If you need to know more call Troy. He is very helpful.
