Having paddled solo in a tandem you'll do just fine in a solo boat.  It will be a treat!  Just be aware of your trim.  When I bow-backwards a tandem my gear is stuffed at the opposite end.  When I paddle a solo most of my gear is behind me.  Trying to turn with the bow skegged from too much weight is an adventure.

One thing to be aware of is how much tumblehome the canoe you get has.  Twice I've been dumped by fighting the tumblehome.  Weight down, slide into it, let it cradle you.  Head between the gunwales.  

My personal fav is the Wenonah Argosy.  I'll take that in wind and wave I wouldn't solo my prospector in.
