Good news! You're staying open minded about the Finkenmeister. I agree that some kayak designs make reasonably good C1's. I would guess that most don't however. I've got the Pyranha H3 245 or 255 as my backup new creeker in case I can't get my hands on the Finkenmeister.
If the Finkenmeister is a successful design and helps Robson, either by improving their status as a boat builder or by (who knows?) making them some money, there may be some other bona-fide and improved plastic C1 designs hitting the market in the future - perhaps more often than the present rate of one every 10 years or so. A few new designs (I'm dreaming now) would probably make better C1 boaters of us all

Most C1ers these days don't know what it was like to paddle a new plastic C1 design.
