Personally i say go sit on a few bikes to get the feel of what you are most comfortable on. Not sure exactly what ur looking for but the vstar 950 is out there also. I like yamaha personally and love my 650. I'm 5'8" about 220 ish and I'm comfortable. Only thing I've done comfort wise is add a set of kuryakyn mini boards in place of the stock pegs. I regularly run at 70 for about a 30 minute ride to work. Haven't ridden an 1100 but I've heard they're a bit tame for an 1100. Piece of advise, while you may not want a big cruiser to handle for a first bike it will be harder to learn on a bike that you're not comfortable on. You can always spend a couple weekends in an empty parking lot somewhere to get acquainted with the bike.
