gfy_paddler,

The Prism is definitely finicky when not loaded correctly.  Bow-heavy going downwind is definitely trouble.   Stern-heavy going upwind also presents challenges.  I found initial stability not-so-hot but, once you get going & if the vessel is loaded evenly, it handles wind & waves in exemplary fashion.  You may want to experiment with your seat position (if that is possible) & then mark the best position when level-loaded.  I can't say that I have had issues with mine when fishing.  Your comment re: preferring the double-blade with the Prism seems to run counter to prevailing preferences that I've seen expressed on QJ.  I use BOTH, preferring a 9 foot double-blade when I am trying to make time and a 54 inch bentshaft when I seek better control.  I go about 6/2", have long arms, and weigh in at 225 lbs (or so) &, with my size in mind, selected the Prism largely based on a recommendation from a guy who is MUCH taller & heavier than me (& owns & has paddled multiple solo canoes to compare to).

I think I'd experiment with seat position (including height) & level-loading before giving up on the Prism.  Good luck!
