I own both the Hyside Mini Max and Paddlecat.
Both are awsome R2 boats.
The Paddlecat is signficantly lighter and rolls signifcantly smaller.
The Mini Max ROCKS as a R2 boat, even better than the paddlecat.
The Mini Max is now my goto R2 class IV-V boat, but the paddlecat rocks class V very well to.
Aire makes great boats too. The Pumas are great R2 boats as well. I have owned 2 Aire Force IK and I was very happy with them.
A handling debate between the Aire and Hyside can be had, but to me it is like debating the handling difference of a high end sports car, they all rock !
Both Aire and Hyside are quality companies that make high quality high performace R2 boats that rock.
BUT for me the lighter weight and more compact roll of the Hyside Hypalon and Neo boats over the Aire boats are important factors
My Paddlecat is small and light enough to fly commercial in a duffel bag meets standard luggage size weight rules.
Fly to Costa Rica and rent paddles there.
I would buy the Hyside product again without hesitation.
Hope that helps.
