I'd 2nd taking a look at a SR Q17.  I rent the canoe for my trips.  My first 2 trips were in aluminum & I could handle the weight OK.  I got a Q17 for the 3rd trip after having back problems in the years in between trips.  
I was concerned it would be unstable, but I was quite comfortable in it tripping and fishing, even with my 11-yr old daughter in the middle sitting on packs.  My 2 more recent trips have been with SR Q18.5 (3-man) due to people considerations.  
I will go back to the Q17 when I can because the Q18.5 is slower - but it hauls a lot & is very stable too.  -Tom
