C50T or C90T

I've decided to go with Suzuki as my first bike.  I'm not planning on riding anyone on the back but I like look of the back seat, saddle bags, & windshield.  I first thought the C50T would make a great first bike but now am having second thoughts after talking to a few more riders.  They are all telling me that in just a few short months I will outgrow the C50 & should go ahead and get the C90.  They are telling me to save my money and just get C90 because I'll want the extra torque when I'm on the highway and I'll be happy with this bike for a long time...not just a few months.  I'm not sure about this and really don't want to spend the extra $$$ for the 90 right now but then again I don't want to be the one wishing I got something else either.
