Thanks all for responding. I ended up getting the adventure. And I also got the Kokatat drysuit
as featured here;
http://www.kokatat.com/product_detail.asp?code=gmerThe suit has worked out great, the biggest issue with it is that the neck collar was so tight I was starting to get sick

I followed the recommendation of several people which said to take a pan and push it through the collar and leave it for a week.
That has reduced the tightness to a point that it is acceptable.
I have taken the yak out several times in the last few weeks, and it is always around 34 or lower, no problems at all staying warm!
And the Adventure flies! All normal paddle boats hate me

Thanks,
Hank.
