Hello Erin,
nice to hear from you. We have paddled the west fork of beaver creek and Cuyahoga Kent section together.

The only thing I know of the rio is it is a ABS style plastic. Stronger than fiber glass but not as strong Rotomolded polyethylene.

In the long run with rivers like Beaver Creek and Mohican that have rocky bottoms is the ABS will start to crack quicker then the Rotomolded polyethylene.
But knowing how good of a paddler you are will also make the abs last longer.

Also on the up side the abs is lighter than Rotomolded polyethylene.

I can use Ken and Cheryl as a good example, when they do lakes or parts of the Mahoning they use an abs style plastic kayaks that are super light. Any time they might do shallow water or more rocky water they switch to the heaver plastic kayaks.

Hope this help, not sure if it will
Mike
