Did you ever make a decision? I have been looking at both of them with interest (Im not in the market for at least a year) but after talking with a friend of mine with a Hypalon dink and the problems he has had with minor repair PVC seems to be a better option
Don't know if this might interest you, but I built a folding dingy and love it.
Will hold 2 people and rows like a champ.
Can use up to 5hp, but I like quite.
Stable enough to stand in, and I used clear, so I can see down to the bottom of the water (if water is clear).
Light (supposed to be around 24pds, but I ended up 50pds).
Still nice and easy to carry and stow away.
If you would like pictures just let me know.
