Ahoy Andrus,
Help may be nearer than you think. Several (three?) members of the Delaware River chapter TSCA have already started, or are about to start, their own CS-17s. Contact me privately and I can try to put you in touch with them.
We meet on the first Tuesday monthly at Red Dragon Canoe Club, Edgewater Park, NJ. Drop by or take a look at our website: www.tsca.net/delriver.
